Cybersecurity That Understands How You Operate
We tackle security from three directions at once: people, devices, and accounts. Employees are trained with phishing simulations and quick lessons so they learn to spot attacks before they spread.
Devices are protected with Endpoint Detection and Response, which monitors and shuts down ransomware or malware in real time. Identities are secured with Identity Threat Detection and Response, catching suspicious logins and account takeovers before they turn into a breach. By layering protection this way, we cover the gaps attackers look for and keep your business working without disruption.

If I'm not out bicycling, I like to watch hockey (go Penguins!), dive deep into the New York Times crossword puzzle archive, or play tennis with my wife.
