We work with a small number of firms whose capability sits alongside our own. Each relationship is written down, bounded, and disclosed where a client engagement touches it.

Trusted thinking for consequential decisions.
Cerebellum is proud to list Visa Inc. among its partners. The relationship reflects a shared expectation that high-stakes decisions should be supported by rigorous evidence, clear judgment and discretion. It also carries particular meaning for the firm: ENGRAM spent 11 years at Visa, working across cyber intelligence and fraud defense at global financial scale before bringing that experience into Cerebellum.
“Cerebellum’s work is exceptional: discreet, rigorous and built to give senior decision-makers confidence before consequential commitments are made.”
Shared with written permission. The executive’s name remains confidential by request.

Cerebellum maintains an active partnership with ThreatCanary, a next-generation cyber AI platform that replaces static, CVE-bound scanning with dynamic, AI-driven vulnerability research and adversarial security analysis. We are an authorised product vendor and reseller of ThreatCanary services and products.
The relationship is publicly endorsed by ThreatCanary and by Matt Flannery, Co-Founder of ThreatCanary and A/Director of Offensive Security for the New South Wales Government, whose work spans red-team offensive cyber operations, APT-level threat detection, government-sponsored vulnerability research and global security leadership. The endorsements are visible on the LinkedIn profile of principal WORMWOOD.
