SNOW Endpoint Sensor and Round-the-Clock Threat Hunting for APT Defense

Arc4dia is a Canadian security company founded in 2010 by Pierre Roberge, previously a cyber specialist in the Canadian national security community, and it is staffed by former members of the intelligence community. It operates from Dorval, Quebec. Its buyers are enterprises and intelligence agencies whose concern is targeted intrusion by advanced persistent threats rather than commodity malware, which is a different problem from the one most endpoint products are tuned for and one that assumes a patient, well-resourced attacker.

SNOW is a host-based sensor that runs covertly on workstations, laptops, servers, phones, and tablets, integrating with an existing network rather than requiring it to be rebuilt. Telemetry from every endpoint feeds SNOWboard, a single command console that gives analysts visibility across the estate and drives investigation and response. Snow Cloud provides the backing infrastructure. The product is built for continuous monitoring and rapid response: detect the activity, investigate what it belongs to, and act on the endpoints involved.

The company pairs the platform with services drawn from the same background: malware reverse engineering, forensic analysis, and counter-APT training for customer teams. That combination positions it for organizations that want an operator's judgment alongside the tooling rather than a product to run themselves. Its emphasis on covert sensor operation is a direct answer to intruders who look for the security agent first, and it sells into a market where discretion and analyst pedigree carry weight alongside detection coverage.
