Hire a Fractional CISO to protect your business. Senior security leadership, compliance expertise, and risk management—at a fraction of full-time cost.
A Fractional CISO (Chief Information Security Officer) is an experienced security executive who works with your company on a part-time basis—typically 1-3 days per week. You get strategic security leadership, compliance expertise, and risk management without the commitment and cost of a full-time hire.
Unlike security consultants who perform one-off assessments, a fractional CISO becomes your security leader. They build and own your security programme, manage risks, drive compliance, and ensure security enables your business rather than blocking it.
"Security is no longer optional. A fractional CISO ensures you're protected without breaking the bank."
Many companies see security as a blocker—something that slows things down and adds cost. A good fractional CISO turns this around. They implement security that enables the business: winning enterprise deals, building customer trust, and protecting against real risks without unnecessary bureaucracy.
Core responsibilities your fractional CISO will own
Develop security strategy aligned with business objectives. Create roadmaps that balance risk, cost, and business agility.
Lead compliance programmes—SOC 2, ISO 27001, GDPR, PCI-DSS. Manage audits and ensure certifications are achieved and maintained.
Identify, assess, and manage security risks. Build risk frameworks and ensure the business makes informed risk decisions.
Oversee security operations—monitoring, detection, and response. Ensure threats are identified and addressed quickly.
Build and test incident response capabilities. Lead response when incidents occur and ensure lessons are learned.
