Is your cybersecurity environment creating challenges like these?
Cybercrime's become so complex, we don't know where we're at risk.
We can't tell if our current cybersecurity measures are sufficient.
We aren't doing enough preventative maintenance or monitoring.
We're struggling to meet our industry's compliance requirements.
Our team's at risk — they don't follow security best practices and can't spot threats.
Is our Microsoft 365 cloud environment safely configured? Are our backups secure?

An NSI managed cybersecurity plan will help.
It used to be enough to install antivirus software and firewalls, and maybe run an annual security awareness class. Now, you need constant monitoring and proactive measures that adapt to today’s evolving threats. By partnering with NSI, you will be protected 24/7 by a cybersecurity plan customized to your needs and goals.
Serving Connecticut for more than 40 years, we’ve been creating solutions that enhance security and reduce downtime, all while eliminating unnecessary costs. You’ll be able to implement advanced security measures such as encryption, multifactor authentication, and security audits that protect your information and build trust.
There’s a lot of jargon to understand and constant change. But the approach is simple:
- Make it really hard for cybercriminals to penetrate your systems.
- Make it easy for us to detect and react if cybercriminals attack.
- Apply fast and effective response protocols to minimize potential damage.
