Recurring technical activities include vulnerability scanning and penetration testing, continuous monitoring of systems, incident case management, and production of audit-ready documentation. The firm provides packaged external network vulnerability scans as a purchasable service and issues regular threat reports that summarize observed incidents. A CPA-led practice provides audit-focused delivery for attestations and compliance engagements. Services emphasize integration of assessment outputs into remediation plans and alignment of technical controls with compliance frameworks.
