Pros

“It helps save time by making it easier to manage multiple devices from one place, especially for updates, scripts, and troubleshooting.”

Basel E.

IT Manager

“This is great for small and medium-sized companies that need software to control hardware/software inventory, in addition to allowing you to connect to an Active Directory server to search for machine information and even perform deployment on machines.”

Wanderlei H.

IT Analyst

“Products of their SOC 2 Type II, ISO 27001, and GDPR certifications, Action1 offers multi‑factor authentication, AES‑256 encryption, and even HackerOne‑backed penetration testing.”

Shane G.

Director, Information and Marketing Technologies

Pros

“For one, this is a subscription that automatically renews for the full price unless you are lucky enough to remember to call and cancel before the renewal date.”

Fred P.

owner

“There was no need to search Windows for similar performance and cleaning operations as it was all there in a single package of software.”

Fred P.

owner

“Easy to use and seems to do a good job, but watch out for extra fees!”

JOHN R.

President

Cons

“FTP-The only thing I missed from the transfer from Itarian was the ability to access folders from each machine to move user files to replacement PCs that I was working on.”

Lonie P.

IT Manager

“The policy management for Windows, and the MacOS support are missing some features which I am used to with more expensive endpoint management suites.”

Noel H.

IT Consultant

“For example one laptop has come out of a cupboard and tripped 500+ vulnerabilities which then hides the ones that work the other way and effect 500+ computers.”

Adam L.

ICT Network Management

Cons

“After 20 minutes of a hard sell to purchase 3 years in advance before I even loaded the program, I was completely turned off and requested an immediate refund, then removed the unactivated program from my PC.”

Fred P.

owner

“The program said it removed a lot of bad stuff but couldn't be verified.”

Fred P.

“did not removed 3 trojans viruses "W64/Trojan2.QYBK" W32/Trojan.”
