Leadership, compliance operations, and engineering

A security team that takes ownership of the work

Your founder or CTO should be able to get back to building while security reviews, controls, and audit preparation keep moving. TSC Security combines fractional CISO leadership, GRC operations, and security engineering in a working team, with scope matched to your business and existing capabilities.

Who this helps

  • Venture-backed SaaS companies from seed through growth
  • Founders and CTOs whose security work is competing with product work
  • AI and healthcare technology companies navigating customer security reviews and compliance requirements
  • SaaS companies facing demanding buyer requirements
  • Teams whose compliance program needs an accountable owner

Problems it addresses

  • Security questionnaires and evidence requests are pulling founders from product work
  • Audit preparation and recurring controls lack a clear owner
  • Buyers need accurate answers about controls and remaining gaps
  • Technical safeguards need an owner and an implementation plan
  • The company needs an operating program before it is ready to hire internally

Choosing a security partner

Questions worth asking any provider

  • Who owns security decisions and the roadmap?
  • Who runs recurring controls, evidence, and audit coordination?
  • Who implements technical changes, and which work stays with our team?
  • Who handles buyer reviews and owns the accuracy of the answers?
  • Who maintains the program after the first audit?

What the work includes

Security leadership

Set priorities around business risk, own the roadmap, explain decisions to leadership, and join the buyer conversations that need a security leader.

GRC operations

Run agreed controls, maintain policies and evidence, coordinate audit preparation, and keep the program working between audits.

Security Engineering

Work with engineering and IT on cloud, identity, endpoints, vulnerabilities, and secure development. Hands-on implementation is included where it is part of the agreed scope.

Buyer security reviews

Coordinate questionnaires, evidence requests, and diligence calls. Give buyers accurate answers about today's controls and the work on the roadmap.

Buyer security reviews

Answers grounded in the work

We explain what is in place today. When work remains, the answer describes a practical plan, an owner, and a date so buyers can understand what they are relying on and what is still being improved.

The program continues after the audit. Evidence stays current, controls keep running, and the roadmap changes as your company and risks change.

Frequently asked questions

What is a fractional security team?

An external team that provides the security roles a growing company needs: security leadership, GRC operations, and security engineering. It works alongside your people on an ongoing basis, at the level of involvement the work requires.

What does our leadership still own?

TSC Security operates the agreed security work and recommends priorities. Your leadership makes security decisions, accepts risk, and remains accountable for the program; your technical teams retain ownership of their systems.

How is this different from one security hire?

One hire usually brings depth in one role. A fractional team combines security leadership, GRC operations, and security engineering, with the mix adjusted to the work your company needs.

When should we hire internally instead?

An internal hire makes sense when the ongoing workload requires a dedicated role or a specific skill set. TSC Security can help clarify that role and support a handoff when you are ready to hire.
