Cons

“Instead, they pulled a bait-and-switch and dumped my account into a 30-day trial. When I served them a formal Notice of Breach [sensitive content hidden], their engineers immediately pushed a silent "ninja patch" to artificially tag the bypassed payloads in my logs, actively trying to cover their tracks.”

Mike H.

Incident Commander-DevSecOps Administrator

“Bold-faced lying and running a cover-up while leaving endpoints exposed is a massive ethical failure.”

Mike H.

Incident Commander-DevSecOps Administrator

“This was my first foray into setting up a SMB Internet Security program, and as such there was a pretty steep learning curve for me to figure out what the do's and don'ts of setup are.”

Matthew C.

IT Manager

Cons

“Unable to detect and prevent zero-day ransomware attacks.”

Timothy C.

IT Engineer

“It consumes significant amount of storage space & powerChallenge in integrating with non-Microsoft environmentsSometimes it alerts the standard activity as potential threats, this lead to investigation & wasting of time”
