M&A Cyber Due Diligence Built for Clear Decisions

Practical deal risk visibility

Security Review

See Exposure Before Close

Understand the target company’s current security posture before valuation, closing, or integration decisions move forward. Perimetra reviews core systems, security tools, endpoint coverage, email controls, cloud settings, and known vulnerabilities to identify exposure that could affect the transaction.

Findings are written in practical business language, with priority levels, remediation paths, and clear evidence so decision makers can act quickly.

Email and Identity

Reduce Access Risk Fast

Identity and email systems often carry the highest operational exposure during a transaction. Perimetra reviews user access, mailbox protections, authentication practices, administrative privileges, and business email compromise exposure to show where sensitive data or financial workflows may be vulnerable.

You receive clear recommendations that support safer access decisions before and after close.

Endpoint Posture

Know What You Inherit

Endpoint and infrastructure reviews help you understand what devices, servers, tools, and management practices are being inherited. Perimetra checks endpoint protection coverage, patching posture, device visibility, system maintenance, and infrastructure dependencies that may affect security or uptime.

The result is a practical view of what is protected, what needs work, and what should be prioritized during integration.

Backup Readiness

Protect Continuity Plans

A strong deal review should include backup, recovery, and business continuity readiness. Perimetra evaluates whether critical data is protected, whether recovery documentation exists, and whether current backup practices can support operational resilience after the transaction.

This helps you understand downtime exposure, recovery gaps, and the practical steps needed to reduce disruption after close.

Risk Reporting

Report Findings Clearly

Cyber findings only matter if they are clear enough to influence the next decision. Perimetra organizes due diligence results into plain-language reports with evidence, risk context, business impact, and remediation priorities.

You get proof in every report, including what was reviewed, what was found, what should happen next, and which items may affect deal timing, cost, or integration planning.

Remediation Plan

Act After the Review

When the transaction moves forward, Perimetra can help turn due diligence findings into a structured remediation plan. Support may include endpoint protection, email security, vulnerability management, cloud security, monitoring, vendor coordination, backup improvements, and ongoing IT guidance.

This creates a practical path from assessment to protection without adding unnecessary bureaucracy.

Know the Cyber Risk Before You Sign

M&A cyber due diligence gives you a clear picture of the technology and security exposure behind a potential transaction. Perimetra reviews the target environment with an implementation mindset, not a theoretical checklist, so findings connect directly to business impact, deal timing, remediation cost, and post-close integration risk.

You receive plain-language insight into endpoints, email security, identity access, cloud configuration, backup readiness, monitoring coverage, vulnerabilities, and vendor dependencies. The goal is simple: help you understand what you are inheriting, what needs attention, and what can be fixed quickly without slowing the deal process.
