Independent buyer-side cyber advisory

Cybersecurity advisory for high-stakes decisions.

Much cybersecurity advisory is shaped by the vendor side of the market: how to pitch, position, and sell. Straylight is shaped by the operator and buyer side — building intelligence capabilities, tracking adversaries, evaluating products, and deciding what would actually work under pressure.

We help clients test claims, sharpen decisions, and close the gap between strategic ambition and operational reality.

When we're useful

Most useful when the decision is important, the claims are difficult to test, and the cost of getting it wrong is high.

Who we advise

Advisory from the buyer side, regardless of who's in the room.

Cybersecurity companies

For founders preparing for serious buyers.

Founders and leadership teams preparing for enterprise, industrial, government, or national-security buyers who will test claims hard.

Typical focus: positioning, proof-of-concept readiness, buyer objection mapping, procurement narrative, GTM pressure-testing.

Engage before a major sales push, government-market entry, strategic partnership, fundraise, or board positioning decision.

Investors

For investors testing cyber claims before conviction.

Venture, growth, and strategic investors evaluating cybersecurity companies, technical claims, buyer adoption risk, and market substance.

Typical focus: technical credibility testing, market timing, buyer willingness to adopt, competitive landscape, management strength.

Useful when the company sounds credible and the real question is whether serious security teams will buy, deploy, and renew.

Public sector & critical infrastructure

For leaders making high-consequence capability decisions.

Public-sector, national-security, and critical-infrastructure leaders making high-consequence cyber and intelligence capability decisions.

Typical focus: requirements definition, supplier evaluation, operating models, adoption risk, operational reality versus proposal claims.

Before major capability investments, supplier evaluations, or intelligence programme redesigns.

How we work

Principal-led advisory. Direct judgement.

Limited engagements

We intentionally limit active work to a small number of concurrent engagements to preserve principal-level involvement and focused delivery.

Direct engagement

We work directly with clients, not through intermediaries. Every project receives the principal's full attention and judgement — not a junior team with occasional senior input.

Clear outputs

Every engagement produces defined deliverables — memos, diligence reports, operating models, board briefings, or strategic counsel — with clear success criteria from the outset.

Conflict screening

We screen every engagement upfront for conflicts of interest and work with one side per engagement. Any concerns are raised before substantive discussion begins.

Built from the buyer side

We've built programmes, tracked adversaries, and led procurement evaluations. Our counsel is grounded in operational reality — not vendor claims, not consulting theatre.
