Cyber Castellum is a cybersecurity consulting firm that helps public and private sector organizations identify weaknesses across infrastructure, applications, and cloud environments, then prioritize practical remediation. Its work spans regulatory readiness, technical testing, governance, and executive advisory, with an emphasis on reducing cyber risk rather than treating compliance as a box-checking exercise.
The firm positions itself as an independent team of cybersecurity consultants and subject matter experts serving government and commercial organizations. Cyber Castellum supports clients with VAPT, compliance consulting, application security, virtual CISO leadership, cloud risk assessment, and policy and governance work, backed by broader expertise in areas such as security project management, software supply chain risk management, incident response, and threat hunting.
Offerings, Capabilities, and Integrations
Cyber Castellum combines governance, risk, and compliance consulting with hands-on security assessment and application security services. It helps clients assess current environments, identify vulnerabilities, build policies, formalize governance, and translate findings into remediation roadmaps. Its broader consulting approach also covers secure development practices, vendor risk evaluation, incident response preparedness, and security program planning.
The firm works across a wide range of security and compliance frameworks, including NIST CSF, NIST SP 800-53, CMMC, FISMA, HIPAA, PCI-DSS, IRS Pub 1075, ISO 27001/27002, SOC 2, NERC-CIP, CIS Controls, and CSA CCM.
