Sidechannel Advisory (Retainer)

Your private channel to a seasoned security leader


What Sidechannel Is

An ongoing, high-access advisory relationship for CTOs and founders who want rapid, credible answers to their cybersecurity and risk challenges.
No middlemen, no decks, no waiting for a consultant to get back to you — just direct access to Craig Balding, former Barclays Group Security CTO and GE Red Team lead.
