Executive Summary
Cyber incidents require calm coordination, preserved evidence, and practical decisions.
OC Security Audit helps organizations respond to suspected compromise, ransomware concerns, account takeover, cloud security events, data exposure, and business disruption without losing sight of executive risk, technical containment, compliance obligations, and recovery priorities.
Service Scope
Incident response advisory built for business leaders and technical teams.
We help your team decide what to preserve, what to contain, what to communicate, and what to fix after the immediate event is stabilized.
Evidence Preservation
Protect Microsoft 365, Azure, endpoint, firewall, VPN, email, and identity evidence before critical logs disappear.
CISO Coordination
Support communication between executives, IT staff, MSPs, legal counsel, insurance providers, and vendors.
Root-Cause Review
Connect incident indicators to identity, endpoint, cloud, network, backup, patching, logging, and access-control gaps.
Executive Reporting
Create clear incident summaries, timelines, business impact notes, control gaps, and remediation priorities.
Post-Incident Roadmap
Turn lessons learned into practical remediation work, validation steps, policies, and future readiness improvements.
When To Call
Request help before evidence is overwritten or decisions become harder to defend.
Account or email compromise
Suspicious inbox rules, MFA fatigue, impossible travel, OAuth abuse, executive mailbox compromise, or wire-fraud concern.
Ransomware or malware concern
Encrypted files, unusual endpoint behavior, lateral movement signs, backup concern, or business interruption risk.
Network or data exposure
Unknown remote access, firewall/VPN anomalies, exposed systems, log alerts, vendor access risk, or suspected data leakage.
Response Path
A practical CISO-led path from incident to recovery.
Assess
Clarify what happened, which systems are involved, and what evidence must be protected.
Contain
Coordinate account, endpoint, firewall, VPN, cloud, email, and vendor access actions with your IT team.
Preserve
Document timelines, logs, screenshots, alerts, artifacts, owners, and decision points.
Report
Prepare executive-friendly summaries for leadership, cyber insurance, legal, compliance, or board review.
Remediate
Prioritize identity, endpoint, backup, patching, monitoring, and access-control improvements.
Validate
Review readiness controls, tabletop lessons, and evidence practices before the next event.
Microsoft 365, Azure, Firewalls, and Business Systems
Digital forensics advisory across the systems that usually decide the story.
Incident response work often depends on Microsoft 365 audit logs, Entra ID sign-ins, Conditional Access changes, endpoint alerts, firewall records, VPN logs, email security events, backup status, and user activity timelines. OC Security Audit helps connect those technical details to a clear incident narrative and remediation plan.
Microsoft 365 Incident Review
Mailbox compromise, admin changes, OAuth consent, suspicious sign-ins, mail forwarding, and SharePoint/OneDrive exposure.
Azure and Cloud Security Review
Identity, privileged roles, logging, storage exposure, workload risk, and cloud configuration concerns.
Firewall, VPN, and Remote Access Review
Remote access anomalies, exposed services, rule changes, denied traffic, and suspicious connection patterns.
Implementation And Recovery Support
From incident findings to practical remediation through IT Perfection.
OC Security Audit focuses on incident response advisory, cybersecurity control review, evidence, and executive guidance. When the response roadmap requires hands-on implementation, IT Perfection can support the operational follow-through as a separate managed IT and project delivery company.

FAQ
Incident response and digital forensics questions.
What should we do first if we suspect a cyber incident?
Preserve evidence, avoid unnecessary system changes, document what was observed, identify affected accounts or systems, and contact a qualified incident response advisor before logs or artifacts disappear.
Does OC Security Audit replace legal counsel or cyber insurance guidance?
No. OC Security Audit provides cybersecurity incident response advisory, evidence guidance, technical review, and executive reporting support. Legal, privacy, regulatory, and cyber insurance decisions should be coordinated with the appropriate counsel and carriers.
Can you review Microsoft 365, Azure, firewall, and endpoint evidence?
Yes. The advisory process can review Microsoft 365 audit logs, Entra ID sign-ins, Azure activity, firewall/VPN records, endpoint alerts, email security findings, and related artifacts to support a clearer incident timeline.
What happens after the incident is contained?
OC Security Audit can help document root cause, control gaps, evidence, and remediation priorities. When hands-on IT implementation is needed, IT Perfection can support managed IT, Microsoft 365, Azure, endpoint, backup, network, and project work as a separate operational provider.

After containment and recovery
Convert incident lessons into stronger readiness and governance
Once the immediate investigation is stable, use incident response planning to revise command roles, escalation thresholds, communications, evidence procedures, insurer coordination, and tabletop scenarios. Corrective actions that span identity, logging, backup, cloud, vendors, or policy can move into the cybersecurity program roadmap.
Material lessons, overdue actions, and accepted residual risk should be summarized through executive cybersecurity reporting. Use the free Incident Recovery Readiness Assessment for initial guidance and review the response approach with Ali Hassani, CISO.
