The MSP Pentesting Playbook: How to Offer Security Testing as a Service

Your SMB clients need penetration testing. Regulatory requirements are tightening, cyber insurance questionnaires are getting more specific, and clients are starting to ask whether their systems have actually been tested. The problem is that traditional pentesting does not fit the MSP model. Engagements cost £10,000 to £25,000, take weeks to deliver, require subcontracting to specialist firms, and destroy your margins. There is a better way. AI pentesting lets you offer security testing as a managed service with the economics that actually work for your business.

The Opportunity Your Competitors Are Missing

Most MSPs do not offer penetration testing. They know their clients need it, but the delivery model has never made sense. You either subcontract to a pentest firm (and pass through most of the cost with a thin markup), or you hire a dedicated pentester (at £60,000-£90,000 salary, which needs a lot of clients to justify). Neither option scales. Neither fits the recurring monthly revenue model that MSPs depend on.

This creates a gap. Your clients go elsewhere for pentesting, or worse, they skip it entirely and hope for the best. Either way, you are leaving revenue on the table and missing an opportunity to deepen client relationships. Security testing is one of the highest-value services you can offer. When you are the one finding and fixing vulnerabilities, you become indispensable.

The MSPs who figure this out first will have a significant competitive advantage. Security is moving from a “nice to have” to a board-level concern for even small businesses. The MSP that can offer continuous security validation alongside their existing managed services wins the contract. The one that says “you will need to find a separate pentest provider” is already behind.

The Old Model: Why Subcontracting Fails

The traditional approach looks like this. A client asks for a pentest. You reach out to a pentest consultancy who quotes £12,000 for a web application assessment. You mark it up to £15,000 and pass it through. The consultancy schedules the work for three weeks out because they are booked. The test takes a week. The report takes another week. Six weeks after the client asked, they get a PDF.

Your margin on the engagement is £3,000 for six weeks of coordination work, client management, and back-and-forth on scoping and scheduling. That is not a sustainable service line. It is project work masquerading as managed services. It does not recur predictably, it does not scale, and it ties up your account management team every time a client needs a retest.

Worse, you have no control over quality. The consultant's report goes to your client with findings you have not validated. If the report is thin, your client blames you. If the remediation advice conflicts with your existing architecture recommendations, you are stuck in the middle. The subcontracting model puts you in a coordination role rather than a delivery role, and that is not where MSPs create value.

The New Model: AI Pentesting as a Managed Service

Autonomous AI pentesting changes the delivery model entirely. Instead of subcontracting each engagement, you run scans yourself through a platform that handles the technical complexity. The AI agents perform the same depth of testing that a manual pentester would: reconnaissance, vulnerability discovery, exploitation, privilege escalation, and lateral movement. They produce professional reports with CVSS scoring, CVE mapping, proof-of-concept evidence, and actionable remediation guidance.

The difference for your business model is transformative. There is no scheduling delay, because scans run on demand. There is no consultant availability bottleneck. There is no weeks-long wait for a report. You initiate a scan, results come back in hours, and you deliver findings to your client the same day. The speed alone changes the client conversation from “we can schedule your annual pentest for next quarter” to “we tested your application this morning and here is what we found.”

More importantly, the cost structure enables recurring revenue. Instead of a £15,000 one-off engagement once a year, you offer continuous security testing as part of a monthly retainer. The client gets better security (tested monthly instead of annually), and you get predictable, high-margin recurring revenue.

How to Price It: Three Models That Work

Model 1: Bundled with your managed services retainer. Add security testing to your existing monthly package at a £300-£500 uplift per client. Position it as “continuous security validation” that runs monthly alongside your existing monitoring, patching, and management. This is the simplest sell because it does not require a separate purchase decision. It becomes part of the overall managed service.

Model 2: Per-scan pricing for project work. Charge £500-£1,500 per scan for clients who want ad hoc testing rather than a retainer. This works well for clients with compliance deadlines, new application launches, or post-incident validation needs. Your cost per scan on Revelion is a fraction of that, so margins stay healthy even on one-off engagements.

Model 3: Tiered security packages. Create bronze, silver, and gold security tiers. Bronze includes quarterly scans, silver includes monthly scans with remediation support, and gold includes weekly scans with priority remediation and a dedicated security review call. This gives clients clear upgrade paths and creates upsell opportunities over time as their security maturity grows.

The model you choose depends on your client base and how your existing services are structured. All three work. The key is positioning pentesting as a recurring service, not a one-time project.

White-Label Reports: Your Brand, Your Client Relationship

Revelion's MSP plan includes white-label reporting. The professional pentest reports that go to your clients carry your branding, not ours. This matters because the report is the deliverable your client sees. It is what they show to their board, their auditor, or their insurance provider. When it has your logo on it, you own the relationship and the perceived value.

Each report includes an executive summary for non-technical stakeholders, detailed technical findings with CVSS scores, proof-of-concept evidence showing exploitability, and specific remediation steps. You can review and annotate findings before sending them to clients, adding your own context about how the findings relate to the client's specific environment and your remediation recommendations. This turns a raw scan output into a consultative deliverable that reinforces your expertise.

Managing Multiple Clients: The Portal

Running pentests for one client is straightforward. Running them for 25 clients requires proper multi-tenancy. Revelion's MSP plan includes a client management portal that supports up to 25 separate client environments. Each client gets their own workspace, scan history, and reporting timeline. Client access is PIN-protected, so you can grant clients read-only access to their own results without exposing other clients' data.

From your dashboard, you get a single view across all clients. Which clients were last scanned and when. Which have open critical findings. Which are due for their next scheduled test. This operational visibility lets you manage security testing at scale without it becoming an administrative burden. Schedule scans during off-peak hours, review results in the morning, and deliver findings to clients before lunch.

The portal also gives you trend data. You can show clients how their security posture has improved over time: fewer critical findings, faster remediation times, reduced attack surface. This is the kind of reporting that justifies ongoing retainers and makes contract renewals straightforward.

Positioning It to Clients

The pitch to clients is simple: “We are adding continuous security validation to your managed services. Instead of a one-off pentest once a year that costs five figures and is outdated within weeks, we test your systems regularly and fix what we find as part of our ongoing management.”

Focus on outcomes, not technology. Clients do not care whether the testing is done by a human consultant or an AI agent. They care about whether their systems are secure, whether they can prove it to auditors and insurers, and whether vulnerabilities get fixed quickly. Frame the conversation around risk reduction, compliance readiness, and insurance eligibility rather than the technical mechanics of how testing works.

For clients with compliance requirements, emphasise the documentation trail. Every scan produces a timestamped report with detailed findings, CVSS scores, and remediation evidence. This is exactly what auditors and insurance underwriters want to see. Regular testing with documented results is a stronger compliance posture than a single annual report, and it can reduce cyber insurance premiums.

The Revenue Maths

Let us work through a realistic scenario. You have 10 SMB clients. You add security testing to their retainer at £500 per month per client. That is £5,000 per month in new recurring revenue, or £60,000 per year. Your cost for Revelion's MSP plan is £299 per month. Even accounting for the time your team spends reviewing results and coordinating remediation (call it 2-3 hours per client per month), the margins are strong.

Compare that to the subcontracting model. Ten clients, each getting one annual pentest at £15,000 pass-through with a £3,000 markup, generates £30,000 in project revenue per year. Less predictable, lower margin, more coordination overhead, and your clients only get tested once. The AI model generates twice the revenue with better margins and a superior client outcome.

Scale it further. At 25 clients (the MSP plan cap), £500 each per month yields £150,000 in annual recurring revenue. That is a meaningful service line built on a £299 monthly platform cost. The unit economics improve with every client you add.

Getting Started: Practical Steps

Step 1: Start with your own infrastructure. Before selling to clients, run Revelion against your own systems. Understand the scan workflow, review the reports, and get comfortable with the findings format. This also lets you fix your own vulnerabilities, which is good practice.

Step 2: Pilot with 2-3 friendly clients. Choose clients with a good relationship and a genuine security need. Run scans, deliver reports, walk them through findings. Use their feedback to refine your delivery process and pricing before rolling out broadly.

Step 3: Build your service package. Define what is included: scan frequency, report delivery, remediation support, review calls. Create a one-page service description that you can include in proposals and contract amendments.

Step 4: Update your contracts. Add security testing to your MSA. Include scope limitations (testing is limited to agreed-upon targets), liability clauses (standard for pentesting services), and clear definitions of what constitutes a “scan” versus additional work.

Step 5: Roll out and scale. Add the service to new proposals by default and offer it as an upgrade to existing clients at their next contract renewal. Most clients will say yes when the cost is £500 per month and the alternative is a £15,000 annual engagement.

Differentiation: What Most Competitors Cannot Offer

Most MSPs who offer any form of security testing are reselling vulnerability scanners, not pentesting platforms. There is a significant difference. Vulnerability scanners check for known CVEs and configuration issues. They do not exploit anything, they do not chain findings together, and they do not prove real-world impact. Enterprise tools like Pentera offer more depth, but at price points that make no sense for MSPs serving SMB clients.

With Revelion, you can offer genuine penetration testing, with exploitation, proof-of-concept evidence, and attack chain analysis, at a price point that works for your clients and your margins. That is a meaningful differentiator. When a prospect compares your proposal (which includes continuous AI pentesting) to a competitor's (which includes a vulnerability scan), the difference is visible and compelling.

The security testing landscape is shifting from periodic, expensive, manually-delivered engagements toward continuous, affordable, platform-delivered validation. MSPs who build this into their service stack now will own the client relationship. Those who wait will find their clients going directly to platforms or switching to MSPs who already offer it.
