M&A Cyber Due Diligence Built Around Deal Clarity

Scoped findings for smarter acquisition decisions

Deal Scope Review
Define the deal boundary

Cyber due diligence starts by defining what is actually in scope for the transaction. CSS reviews business units, networks, cloud environments, users, vendors, contracts, regulated data, and sensitive workflows to clarify the cyber boundary before deeper testing begins.

This helps prevent inflated findings, missed obligations, and unnecessary remediation estimates. You get a structured view of what is included, what is excluded, and where additional validation may be needed.

Compliance Review
Spot compliance exposure

For acquisitions involving defense contractors, healthcare groups, financial firms, legal practices, accounting firms, or other regulated organizations, compliance exposure can affect deal value. CSS reviews alignment indicators tied to frameworks such as CMMC, NIST 800-171, HIPAA, GLBA, PCI, ISO 27001, and related obligations where applicable.

The output highlights documentation gaps, control weaknesses, evidence concerns, and areas that may require remediation before or after close.

Asset Discovery
Know what you inherit

Unknown assets create unknown liability. CSS documents systems, endpoints, cloud services, identities, remote access paths, mobile devices, data repositories, and third-party connections that may become part of the buyer’s operating environment.

This review helps identify unsupported systems, unmanaged devices, excessive access, data loss exposure, and integration constraints. The result is a clearer technical inventory for risk scoring, budgeting, and post-close planning.

Control Assessment
Validate key controls

Security control review focuses on how well the target protects users, devices, networks, and data today. CSS evaluates practical safeguards such as MFA, RBAC, privileged user management, endpoint security, patching, DNS filtering, email security, DLP, encryption, logging, and secure remote access.

Findings are presented in plain language with severity, business impact, and recommended next steps so the deal team can act without guessing.

Incident Readiness
Assess resilience risk

Cyber incidents, ransomware exposure, weak backups, and limited monitoring can create material risk after acquisition. CSS reviews available incident history, backup and recovery practices, alerting, logging, EDR/XDR coverage, SOC visibility, and response procedures.

The goal is to understand whether the organization can detect, contain, and recover from common threats. You receive risk context that supports insurance review, integration planning, and immediate remediation priorities.

Remediation Roadmap
Plan remediation clearly

Due diligence should end with a practical action plan, not a stack of technical observations. CSS prioritizes findings by risk, compliance impact, remediation complexity, and deal relevance, then outlines phased next steps for pre-close negotiation or post-close execution.

Recommendations can support budget planning, transition services, vendor oversight, managed security decisions, and board reporting. The roadmap helps you reduce risk without unnecessary rip-and-replace disruption.

What Gets Reviewed During Cyber Due Diligence

Cyber due diligence should identify the risks that can affect valuation, closing conditions, compliance exposure, and post-close integration. CSS reviews the technical and operational areas buyers need to understand before taking ownership.

  • Security program maturity and documented policies
  • Identity, MFA, privileged access, and login auditing
  • Endpoint protection, patching, device hardening, and EDR/XDR coverage
  • Email security, phishing defense, DNS filtering, and data loss prevention
  • Regulatory alignment with frameworks such as CMMC, NIST 800-171, HIPAA, GLBA, PCI, and ISO 27001 where applicable
  • Cloud, Microsoft 365, GCC, GCC High, and data storage considerations
