Protect Your Business from Cyber Threats, Downtime, and Costly Security Incidents
Cyberattacks are becoming more sophisticated, cyber insurance requirements continue to evolve, and a single compromised account can disrupt business operations overnight.
NetTec NSI helps Charleston-area businesses strengthen cybersecurity, secure Microsoft 365, reduce business risk, and improve cyber insurance readiness.
Our approach focuses on prevention, detection, response, and continuous improvement, helping businesses stay secure without sacrificing productivity.
Why Cybersecurity Matters
Many organizations don't discover security weaknesses until after:
A phishing attack succeeds
A Microsoft 365 account is compromised
Ransomware disrupts operations
Cyber insurance requirements aren't met
Sensitive information is exposed
Modern cybersecurity requires more than antivirus software.
Businesses need layered security controls designed to protect users, devices, identities, email systems, cloud platforms, and business data.

Unknown and Unwanted Applications on your Network?
High-risk, unwanted, and even malicious applications are hiding like parasites on many organizations' networks. That's because most next-gen firewalls are failing to do their job. They can't identify specific applications and at best are only able to identify the protocol such as HTTP, HTTPS/SLL, UDP or TCP. Which is of no use to a network admin trying to see what security, compliance, and productivity risks are present on their network. What are these parasitic applications? Why can't next-gen firewalls see them? And what can you do to make sure you identify every single app on your network? Read our whitepaper on how to find and stop them.
