IT Services Company Servicing the DC Metro area Since 1987
Is your network secure? • Are your backups being monitored? • Are you experiencing delayed response times from your IT Vendor? • Would you benefit from a Free Network Security and Backup Audit?
Call (410) 280-3002 now!

Our Free IT Assessment Will:

• Check your firewall’s security settings to make sure you are protected from the latest hacker attacks, worms and viruses.
• Scan for spyware that is secretly stealing bandwidth, jeopardizing network speed, and embezzling confidential information about you, your employees, your business, and your customers.
• Check your network’s back-up system to ensure it is accurately saving all of the critical files and information you cannot afford to lose.
• Verify you have the most up-to-date security patches properly installed; miss one critical update and you’re a “sitting duck” for a cyber-attack.
• Diagnose slow and unstable PCs.
• Scan the Dark Web for your STOLEN credentials!
All free of charge, with no commitment from you!

    • Always very thorough, timely, strong on follow-up and that allows our organization to focus on what we do best.
      I would surmise one of the benefits to our partnership with ICSI, if not the most important, is that we can trust that they always handle items and situations for us as if they were handling them for themselves.
