Key Takeaways
- Arctic Wolf, Critical Start, and Rapid7 run the scanning, while your team usually still applies the patches.
- Optiv fits teams that already scan but need a remediation plan and hands-on help to carry it out.
- TuxCare supplies the actual fixes, including end-of-life security updates and rebootless kernel patches.
- Before signing anything, ask who applies each patch and who verifies that it actually landed.
Search for a vulnerability management service provider and the results lump together four very different kinds of companies. Some sell software your team runs. Some run the program for you. Others assess what you have and help rebuild it, and a few supply the fixes themselves.
The five providers below weren’t picked off a single scorecard. Each one stands for a different way to hand off part of the work, so the useful comparison is within the model that matches what your team can’t absorb. For each provider, you’ll see what it does, where it stops, and how it’s priced.
What a vulnerability management service provider does
A vulnerability management service provider takes on part of the work of finding, prioritizing, and closing security weaknesses. How much of that work actually leaves your plate depends on the model you buy, and the table below shows where each model hands off to your team.
| Model | Who scans | Who triages | Who applies fixes | Typical contract | Examples |
| Tool vendor | Your team | Your team | Your team | Software subscription, often priced by asset | Qualys, Tenable (not profiled here) |
| Managed provider (VMaaS) | Provider | Provider | Usually your team, unless you add a patching option | Subscription scoped by IPs, assets, or servers | Arctic Wolf, Rapid7, Critical Start |
| Assessment-led firm | Varies by engagement | Consultants, working with your team | Your team, or consultants at higher tiers | Project or retainer | Optiv |
| Remediation partner | Your scanner | Your team | Provider supplies patches, and your team or an agent applies them | Per-system subscription | TuxCare |
Tool vendors such as Qualys and Tenable sell platforms that your team operates. Some providers wrap those platforms in a managed service, which is exactly what Critical Start does with Qualys VMDR.
Assessment-led firms such as Optiv work a little differently from the other three models. They review your program, build a remediation roadmap, and at higher tiers supply consultants for hands-on work. If you searched for vulnerability assessment companies, this is probably the category you had in mind.
Read the statement of work: A managed service doesn’t automatically include patching. In the services profiled here, the core scope centers on scanning, prioritization, and guidance, and applying fixes stays with your team unless you buy a higher tier or an add-on. Ask who applies each patch and who confirms it worked. For the broader distinction, see our guide to patch management vs vulnerability management.
Comparing the five providers at a glance
The table groups providers by delivery model. Pricing cells show what each provider publishes, which, as you’ll notice, isn’t much.
| Provider | Model | Best for | Who applies fixes | Pricing |
| TuxCare | Remediation partner | End-of-life software and Linux hosts that can’t reboot easily | Your team or an agent applies the patches TuxCare delivers | Per-system subscription |
| Optiv | Assessment-led firm | Organizations with scanners in place and a stalled remediation program | Your team, or Optiv consultants at the highest tier | Scoped by engagement |
| Arctic Wolf Aurora Vulnerability Management | Managed provider | Teams that want one named team across detection and exposure | Your team with guidance, or automated patching for supported software through the Resolve add-on | Quote-based |
| Critical Start Vulnerability Management Service | Managed provider on a tool vendor’s platform | Buyers who want Qualys VMDR operated for them | Your team, working from Critical Start’s patch lists | Quote-based, three tiers |
| Rapid7 Managed Vulnerability Management | Managed provider | Teams that want scan operations and a monthly review handled for them | Your team, with prioritized guidance | Quote-based |
TuxCare
TuxCare sits in a different category from the other four, so weigh it that way. It doesn’t run a scanning and triage program for you. What it supplies is the patches and security updates for software that’s hard to fix through normal channels, either because it’s past the vendor’s end of life or because the host can’t take a reboot. That makes it a remediation partner, and your team or an agent still does the applying.
What you get
Security updates past end of life with Endless Lifecycle Support
Endless Lifecycle Support (ELS) delivers security updates for operating systems after the vendor’s standard support lifecycle ends. The same model covers language ecosystems, runtimes, and applications after their official end-of-life dates, which matters because a lot of EOL risk hides in dependencies rather than the OS. Updates arrive through a package repository, so your team or its configuration tooling installs them like any other update.
Screened open source packages with SecureChain
For code that’s still under active development, SecureChain swaps public registries for TuxCare-managed ones that serve verified, signed, continuously patched open source packages across JavaScript, Python, Java, Go, Rust, and PHP. Your package managers point at the TuxCare registry instead of the public one, and dependencies install the usual way.
Live kernel patching with KernelCare
KernelCare applies security patches to running Linux kernels without a reboot, so maintenance windows stop dictating when fixes land. The LibCare add-on extends live patching to shared libraries such as OpenSSL and glibc. KernelCare covers 70+ Linux distro versions across the major enterprise Linux distributions, including RHEL, CentOS, Ubuntu, CloudLinux, Proxmox VE, Oracle Linux, Amazon Linux, and Debian. Check the supported list for your exact kernel versions.
Pricing
TuxCare prices its patching products per system. Check the unit, the term, and any SLA add-on when you compare quotes, and confirm current pricing with the TuxCare team.
| Product | Pricing model | Current price |
| KernelCare Enterprise | Per system | Confirm with TuxCare |
| Endless Lifecycle Support | Varies by line | Confirm with TuxCare |
Where TuxCare shines
Fixes stop waiting on a maintenance window, because live patching remediates vulnerabilities on hosts that can’t take a reboot. Unsupported software gets a real source of security updates while the migration waits on hardware, budget, or recertification. And since the patching products work behind whatever scanner you already run, adopting them doesn’t mean ripping anything out.
Where TuxCare falls short
TuxCare won’t own your program. Scanning and triage stay with your team or another vendor, and there’s no analyst bench running things on your behalf. Coverage also leans heavily toward Linux and open source runtimes, languages, and applications. On Windows, it’s limited to selected runtimes such as .NET and PHP, so a Windows-heavy estate will need another provider for broader coverage.
Who TuxCare is best for
Platform leads whose findings stay open because change windows are scarce get value fastest. Owners of end-of-life estates are the other obvious fit, whether that’s a fleet still on CentOS 7 because one stubborn application blocks the migration, or a service pinned to a runtime that went EOL years ago. It also suits teams that already find the issues and simply have no supported fix for them.
Optiv
Optiv sells managed vulnerability scanning as its own service, but the remediation services covered here treat vulnerability management as a program to build or repair. Its consultants baseline where you stand, rank the work, and guide remediation through four phases: discover, prioritize, remediate, and validate. Depth is adjustable. A one-time assessment is the lightest option, and the heaviest puts Optiv consultants inside your team.
What you get
The four phases
Discovery maps your vulnerabilities and the people who own the affected assets, which gives you a baseline. Prioritization ranks findings by risk and turns them into a triage process and a roadmap. In the remediation phase, you pick which services you want Optiv to run. Validation then verifies the results and ties them back into your own metrics and KPIs.
Tiers of advisory support
Optiv’s remediation page lists three levels. Assessment and planning (VMAP) covers an initial workshop, a remediation plan, and point-in-time prioritization. Remediation advisory (VRAS) adds regular plan updates, ongoing prioritization and tracking, program advice, and KPI reporting, all built around weekly client meetings. Remediation advisory plus (VRAS Plus) layers on hands-on technical support and extra staffing to speed the work, with consultants acting as an extension of your team.
Platform deployment and migration help
Optiv also handles deploying, configuring, and tuning vulnerability management platforms, and it has published material on migrating between them. If a tool change is already on your roadmap, that work can sit inside the same engagement.
Pricing
Optiv scopes engagements to the work involved, so your price depends on the tier and the effort required. Ask what the quote assumes about asset count, number of business units, and duration, and confirm current terms with Optiv.
| Offering | Pricing model | Current price |
| Assessment and planning (VMAP) | Scoped by engagement | Confirm with Optiv |
| Remediation advisory (VRAS) | Scoped by engagement | Confirm with Optiv |
| Remediation advisory plus (VRAS Plus) | Scoped by engagement | Confirm with Optiv |
Where Optiv shines
The phased method gives you a clear before and after. Discovery sets the baseline, validation measures against it, and the gap between the two is an easy story to tell leadership. You can also start small with an assessment and add advisory or hands-on support as the program matures, while the deployment, tuning, and migration work covers the platform side of things.
Where Optiv falls short
Advice comes first. Two of the three tiers center on planning, prioritization, and guidance, and hands-on work only shows up at the top tier. These remediation services don’t include running your scans day to day. Optiv sells managed vulnerability scanning separately, so ask whether the two can be scoped together. Regulated buyers should ask Optiv directly for whatever assurance reports and certifications their procurement process requires.
Who Optiv is best for
Security leaders who already have scanners and a backlog that refuses to shrink are the natural fit. Teams planning a platform migration get a partner that can run the tool deployment alongside the program changes. Managers who answer to executives will appreciate walking away with a baseline, KPIs, and validated results that show what changed.
Arctic Wolf Aurora Vulnerability Management
Arctic Wolf introduced Aurora Vulnerability Management in May 2026 as the evolution of its Managed Risk service, so older reviews written under the Managed Risk name describe an earlier version. Aurora VM scans internal and external assets, ranks findings using threat and exploitability context, and pairs all of it with Arctic Wolf’s Concierge Security Team (CST). Arctic Wolf also sells managed detection and response, and the two can share a platform.
What you get
A named Concierge Security Team
The CST is your main point of contact for the service. It learns your risk policies, asset criticality, patching cycles, and service-level objectives, then helps rank what to fix first. When a critical risk turns up, the team supplies guidance and supports you through remediation.
Scanning across networks, endpoints, and cloud
Aurora VM covers internal and external vulnerability scanning, asset inventory, and software misconfiguration checks. On endpoints, the Arctic Wolf Agent adds host-based checks, running CIS benchmark scans and OVAL-based vulnerability scans, and it supports Linux. Cloud posture coverage depends on which of Arctic Wolf’s cloud offerings you add, so ask what’s in scope for your accounts.
Remediation guidance and Resolve
Findings reach you through a portal with dashboards and on-demand reports. Remediation support includes AI-powered guidance, customizable remediation SLAs, ITSM integrations, and rescanning to confirm a fix held. Automated patch deployment comes through the Resolve add-on, which lets teams schedule and apply patches for supported third-party software on hosts running the Arctic Wolf Agent. Its supported-software list runs to roughly 200 entries, nearly all desktop applications such as browsers, PDF readers, and Office. Most are Windows titles, and the dozen or so Linux entries are things like Chrome, Firefox, LibreOffice, and Zoom.
Pricing
Arctic Wolf prices Aurora VM to the scope of your environment and the services you choose. Ask which units the quote counts, whether Resolve is included, and how it’s bundled with any detection services, then confirm current figures with Arctic Wolf.
| Plan | Pricing model | Current price |
| Aurora Vulnerability Management | Scoped to your environment | Confirm with Arctic Wolf |
| Resolve | Add-on to Aurora Vulnerability Management | Confirm with Arctic Wolf |
| Aurora Vulnerability Management with managed detection and response | Packaged with the detection service | Confirm with Arctic Wolf |
Where Arctic Wolf shines
Most of the value sits with the CST, which learns your policies and patching cycles, so you’re working with people who already know your environment. Coverage is wide for a single service, and it’s the only managed provider here with a documented path to automated patch deployment, through Resolve. If you’re also weighing managed detection, Aurora VM can share the platform and the team.
Where Arctic Wolf falls short
Without Resolve, you get guidance and workflow, and your team still deploys the patches. Even with it, Resolve is aimed at desktop software, so server packages and kernel updates stay on your plate. Early budgeting is tricky because Arctic Wolf’s public Aurora VM pages don’t state a pricing unit. Linux detail needs a direct question too: ask which distributions the agent supports and which checks it runs on them.
Who Arctic Wolf is best for
IT directors without a dedicated security team get outside analysts who run scanning and tell them what to fix first. Buyers already shopping for managed detection can cover both needs with one provider and one portal, and teams with hybrid estates get a single point of contact across network, endpoint, and cloud.
Critical Start Vulnerability Management Service
Critical Start starts with the scanner. Its Vulnerability Management Service runs on Qualys VMDR, and Critical Start can either supply the Qualys license or run the service on a subscription you already own. Either way, your team doesn’t have to configure or babysit the platform. Critical Start announced general availability in August 2024.
What you get
Managed scanning on Qualys VMDR
Critical Start’s analysts handle operational monitoring, scheduled scanning, and analysis. Scans cover external and internal targets, using lightweight agents or remote scanners depending on the environment, and you can choose fully managed scans or keep running them yourself.
Prioritization and patch lists
The service ranks findings by risk and turns them into prescriptive patch lists, including vendor-specific and third-party patches, so your team knows what to deploy and where. Customizable vulnerability and remediation reports are part of the package.
A shared console and ticketing links
Results appear in Critical Start’s own platform next to its managed detection alerts, asset inventory, and security control gaps. The service can also connect to your ticketing system to track fixes through to closure.
Pricing
Critical Start’s current services page puts VMS on the same three-tier structure as its MDR services. The tiers are Essentials, Enterprise, and Signature, and each step up adds named contacts, more frequent reviews, and stronger SLA commitments. If Critical Start supplies the Qualys license, the quote covers both scanner and service. Ask what unit the price scales with, and confirm current figures with Critical Start.
| Plan | Pricing model | Current price |
| Essentials | Team-based service, quote-based | Confirm with Critical Start |
| Enterprise | Named CSM and TAM, quote-based | Confirm with Critical Start |
| Signature | Concierge service with an executive sponsor, quote-based | Confirm with Critical Start |
Where Critical Start shines
If you need both pieces, you get Qualys VMDR and the analysts who run it under one agreement, which removes a separate licensing step. Already own Qualys? The service can run on your subscription instead. Teams can pick fully managed scans or keep scheduling their own, and anyone who also buys Critical Start’s managed detection sees vulnerability results in the same console as their alerts.
Where Critical Start falls short
The scanner is fixed. Because the service is built on Qualys VMDR, a team that has standardized on another scanner needs a different route. Critical Start’s public material describes patch lists for your team to work from and says nothing about deploying them. Critical Start’s published SLA terms are also written mostly around alert response times, so ask how they translate to vulnerability work before you sign.
Who Critical Start is best for
Teams that already favor Qualys and want its coverage and scoring without running the platform themselves are the clearest match. Existing Critical Start detection customers get one portal for alerts and vulnerabilities. Lean IT groups that own patching fit well too, as long as they’re happy to work straight from the lists and want someone else to schedule and analyze the scans.
Rapid7 Managed Vulnerability Management
Rapid7’s Managed Vulnerability Management (MVM) puts Rapid7’s team in charge of scanning the IP addresses on your order form and reviewing the results with you every month. The documented scope centers on prioritization and guidance, and on the standard MVM tier your team can also see results in the InsightVM console.
What you get
Monthly scanning and reporting
Rapid7 scans your contracted IP addresses on a monthly cadence and delivers a monthly service report. Once you and your advisor agree on a schedule, Rapid7’s Managed Operations team handles scan configuration, monitoring, verification, and troubleshooting. The entry tier, MVM Basic, covers up to 2,500 IP addresses and runs on Rapid7’s Nexpose engine.
An assigned Cybersecurity Advisor
You meet with your advisor every month to review reports and metrics, and periodic business reviews cover program trends and recommendations. The advisor also supplies monthly remediation prioritization and guidance, which tells your team where to start each cycle.
Console access
On the standard MVM tier, your team can open the InsightVM console to view results and reporting between meetings. MVM Basic doesn’t include customer access to the Rapid7-hosted console.
Pricing
Rapid7 sizes MVM by the IP addresses on your order form, so your quote depends on how many you contract. For current pricing, contact Rapid7 through its MVM page.
| Plan | Pricing model | Current price |
| MVM Basic | Scoped by contracted IP addresses, up to 2,500 | Confirm with Rapid7 |
| MVM | Scoped by contracted IP addresses | Confirm with Rapid7 |
Where Rapid7 shines
Rapid7 writes its scope down, so you can check a quote against a concrete list of deliverables. The monthly advisor meeting gives your team a fixed slot to review metrics and agree on priorities, and on tiers with console access, your staff can dig into results without waiting for the next report.
Where Rapid7 falls short
Patching sits outside the documented scope. The listed deliverables cover prioritization and guidance, and patch deployment doesn’t appear anywhere. The documented scan cadence is monthly, which is a long gap for fast-changing environments, so ask whether the contract allows more frequent scans. Network exceptions are on you as well. If intrusion prevention or a web application firewall could interfere with the scans, you’ll need to allowlist the scan engine’s source IP or run scans from a network location those controls don’t sit in front of, and Rapid7 treats verifying those controls as out of scope.
Who Rapid7 is best for
Security leads with a small team fit best here, especially if they want scans run and reviewed on a schedule and have staff to apply the fixes. IT managers who already own patching can slot the advisor’s prioritized list straight into the process they’ve built. For teams already using InsightVM, the console will feel familiar on tiers that include access.
Choosing a vulnerability management service provider
The right provider depends on which part of the work your team can’t absorb. If nobody has time to run scans and rank the results, a managed provider such as Arctic Wolf, Rapid7, or Critical Start takes that on, and Arctic Wolf’s Resolve add-on goes a step further, into automated patch deployment for supported software. If you have scanners but findings keep piling up, an assessment-led firm like Optiv can help you rebuild the program. And if your open findings sit on end-of-life software or on Linux hosts you can’t reboot, a remediation partner such as TuxCare supplies the fixes.

FAQs
It’s a company that takes on part of the work of finding, prioritizing, and fixing security weaknesses in your systems. Some operate the program for you, some sell software your team runs, some advise on remediation, and some supply patches.
A tool vendor sells software that your team configures and runs. A managed provider operates scanning and triage for you and reports on a schedule. A remediation partner supplies the fixes, such as live kernel patches or security updates for unsupported operating systems.
Vulnerability management as a service (VMaaS) is a subscription in which a provider runs some combination of scanning, prioritization, and reporting for you. Scope varies by contract, and some offerings are co-managed, so check what your team still owns, including patch deployment.
It depends on the provider and the tier. Rapid7’s documented scope covers prioritization and guidance. Arctic Wolf’s Aurora VM centers on guidance and remediation workflows, with automated patching for supported software available through its Resolve add-on. Critical Start supplies patch lists, and Optiv adds hands-on support at its highest tier. TuxCare delivers patches that your team or TuxCare’s own tooling applies.
Managed services are usually scoped to your environment, so providers quote by IP address, asset, system, or engagement. Compare quotes using the same asset count, and ask each provider what counts as one unit. Confirm current figures with each provider, since packages and prices change.
Many providers produce reports that can support an audit, though formats, assurance levels, and what your auditor will accept all differ. Ask for sample reports and current certifications before you commit.
It depends on the job. For fixes on Linux systems that can’t reboot or have passed vendor support, TuxCare supplies live kernel patches and, for supported versions, Endless Lifecycle Support security updates after the original vendor’s standard support ends.
Some third parties sell security updates for operating systems and other software after the original vendor stops supporting them. TuxCare’s Endless Lifecycle Support is one example, and it delivers updates through a package repository. You can check which versions are covered before you plan around it.
