Pros / Cons
  • Really simplifed our patching needs as well as offering live vulnerability data in an easy to digest format, it has helped us to gain visibility across our organisations and provide our technicians with additional tools to support their roles.
  • The fact that you cant automate OS version upgrades (Tried for Win11 25H2) and if you run it manually it is very buggy.

  • What I like about this software is the many useful tools available to clean up a drive of viruses, optimizing the hard drive, boosting speed, repair registry, password safety, and cleaning up system clutter to name a few.
  • I called and got the monthly fees stopped (I think), but I still have several months of payments that they took on my credit card, not reimbursed.
