On a Mission to Make Cybersecurity Simple and Accessible

Cybersecurity is a growing challenge for every organization, regardless of industry or size. We founded SideChannel in Worcester, Massachusetts, on the belief that small and mid-sized organizations deserve the expertise of an experienced CISO, just as much as a larger enterprise, at a reasonable cost. Running those programs across hundreds of organizations, our team of security leaders kept finding the same gaps: unsegmented networks, unmanaged certificates, blind spots in asset inventories. That pattern is what drove us to build Enclave, our zero-trust security platform. Whether you need the strategy, the infrastructure, or both, SideChannel has a path for where your program is today.

Built by security leaders. Operated by the same team

SideChannel's advisory practice has run security programs across hundreds of organizations. That work revealed the same gap every time: the tools available required more architecture, more headcount, and more budget than most programs could support. Enclave was built to close that gap. It is the operational infrastructure SideChannel's own security leaders wished existed, deployable, manageable, and effective without adding headcount or operational complexity. When a vCISO identifies a segmentation problem, a certificate risk, or a visibility gap, Enclave closes it.
