Sintra Advisory is an independent OSINT and strategic-intelligence consultancy serving two audiences that share one problem: decisions that depend on knowing who they are dealing with.

For corporate clients, including investors, acquirers, boards, and counsel, we conduct due diligence, counterparty intelligence, executive vetting, and integrity assessments ahead of investment, M&A, hiring, partnership, and vendor decisions. Every finding is sourced, confidence-rated, and built to withstand scrutiny from a client, a lawyer, or a regulator.

For universities, research institutions, and think tanks, we provide research-security advisory and compliance: foreign-interference risk, dual-use assessment, partner and collaborator screening, and institutional programmes aligned with Horizon Europe security provisions, STRAC, NSPM-33, and UK frameworks.

Named for Sintra and the Quinta da Regaleira: what matters is rarely on the surface.
