Penetration testing for MSPs

ClientMSPOverWatch

What a useful assessment looks like

  1. Define the client boundary

    Name the systems, owners, permissions, and exclusions.

  2. Validate the exposure

    Test agreed applications or networks with a defined escalation path.

  3. Make the handoff useful

    Give the client a prioritized fix list and agree who owns each action.

One scope. Clear responsibilities.

Keep the client relationship and assessment boundaries explicit. Partner terms, white-label arrangements and timelines are discussed individually.

Before authorization
Confirm the client asset owner, written testing permission, third-party exclusions, maintenance windows and a stop-testing contact. Support access alone is not testing authorization.
During the assessment
Agree application, API or network scope, report recipients and an escalation channel for urgent findings. Keep the client and MSP informed under the agreed communication plan.
At remediation
Separate client actions from MSP actions. Review the evidence, assign each fix to an owner, and agree any retest scope and timing in the proposal.

OverWatch Labs is an ISO/IEC 27001:2022 certified company. Certification covers the company’s information security management system, not a guarantee that an assessed system has no vulnerabilities.

“Our client needs a pentest. Where do we start?”

An MSP may manage the environment without having permission to authorize every test. Scope, client consent, and clear roles come before technical activity.

Choose a stage to see the decision and what to prepare. This is an illustrative scenario, not a client case study.

Support access is not testing authorization.

Why this matters

Review reproducible findings with the client and MSP. Set retest scope and timing in the proposal; do not leave responsibility implicit.

Scope the work around your situation.

Partner terms, white-label arrangements, pricing, and delivery timelines are discussed individually. No standing partner program or SLA is implied.
