Vetted Fractional CISO Services

A fractional CISO is a senior cybersecurity executive who joins a company part-time to lead security strategy, compliance, and incident response. The fractional CISO meaning is straightforward: an executive who owns the security function, not a consultant who advises on it. Engagements typically run 10 to 25 hours per week, for as long as the work requires it.

Fractional CISO pricing through Tecla varies by scope, seniority, and depth of the engagement. The fractional CISO cost model is all-inclusive, with no upfront fees, no fees to start the search, and no charges for interviews. The engagement runs at a fraction of the cost of a full time CISO, which is what makes the model cost effective for growth-stage tech companies. Hourly rate models exist elsewhere, but the retainer structure delivers more predictable outcomes.

The scope of the work is similar, strategic leadership over security. The difference is in hours, cost structure, and commitment. A full-time CISO works 40+ hours per week with a six-figure salary and equity. A fractional CISO works 10 to 25 hours per week on a monthly retainer, with no equity required and flexibility to scale up or down.

The what is virtual CISO vs fractional CISO question comes up often. Fractional and virtual CISOs share the same underlying model. vCISO usually implies a virtual, always-available advisory relationship, often bundled with managed security services. Fractional CISO usually implies a leader who embeds part-time in the company, joins the leadership team, and is accountable for the security program.

The fractional CISO vs security consultant distinction matters when choosing an engagement model. A security consultant advises from the outside, delivering assessments and recommendations before handing it off. Fractional CISOs join the leadership team, own the security strategy, and are accountable for the outcomes. When a company needs an executive to run the cybersecurity program, not just review it, the fractional model fits better.

Common triggers include: an enterprise deal requiring SOC 2, HIPAA, or ISO 27001 evidence, an incident or audit finding that surfaced gaps, scaling past the point where ad hoc security is enough, filling a gap between full-time CISO hires, or adding executive-level security judgment when the current team lacks it.

A fractional CISO delivers security strategy for the company. Common responsibilities include the cybersecurity program, compliance and certifications, risk assessments, incident response planning, vendor security review, awareness training, and executive judgment across the business. The fractional CISO runs the security function the way a full-time CISO would, at part time hours.

Fractional CISO benefits include access to executive judgment without a full-time salary, flexibility to scale hours up or down, faster hiring cycles, and pattern recognition across compliance cycles and cyber risks. For growth-stage tech companies, a fractional CISO often brings depth from prior SOC 2 and HIPAA programs that a first-time hire would not have.

Most startups work with fractional CISO consulting firms or fractional CISO firms with matching networks, rather than running an independent search. Fractional CISO consulting operates on retainer, or as a matching network like Tecla. The fractional CISO companies in this space deliver fractional CISO services for startups within days. A fractional CISO consultant from a vetted network typically starts inside two weeks. An independent search takes longer and lacks the vetting depth these engagements require.

Track record matters more than certifications on paper. Look for prior experience running security programs in companies at your stage and industry, depth in SOC 2, HIPAA, or ISO 27001, familiarity with incident response, and a communication style that fits the leadership team. Fractional and virtual CISOs both work, what matters is the fit to the engagement.

Yes. If the fractional CISO engagement does not work within the first 90 days, we replace the leader at no additional cost. The guarantee is standard across every engagement we run.

A fractional CISO delivers executive judgment while the internal team continues to run day-to-day operations. The CISO owns the strategy, the fractional CISO offerings connect to engineering, legal, and the board, and the security team executes against the program. Cadence varies by engagement, but weekly leadership meetings and monthly board-level reporting are typical.

Sometimes. In many engagements, the fractional CISO transitions to a full-time role once the company reaches the scale that justifies it. When that is not the right fit, Tecla runs the executive search for the permanent CISO alongside the fractional engagement.
