If you've caught the news recently, you know that maintaining the security of your business data is tougher - and more critical - than ever. A network assessment from Systems Integration, (also called a "security audit" or "security review"), will ensure that proper security controls are integrated into your technology environment.

Every small business owner knows the importance of their business data. What many don't realize is that while the chances of a major disaster are quite remote, the majority of data loss is the result of small, localized problems. Could your business weather a major equipment failure caused by a tree falling through the roof, a lightning strike or even theft?
Beneath the World Wide Web you know and love is a hidden realm of stolen data, illegal activity, and anonymity. This realm is known as the Dark Web, and for a company that stores personal data about your customers, it can be your worst nightmare.

It is said that the Dark Web is more than 500 times the size of the web that is searchable by Google, and it is where criminals go to gain access to data that allows them to steal identities, money, and more.It is scary to think about, but with Dark Web ID and Systems Integration, you can put your nightmares to rest.

If you want your business to save downtime, be protected from cyber crime, and increase overall productivity- call Systems Integration. Speak on the phone with a real human from Connecticut. They are super responsive, I can call literally 24/7/365 and someone will help. I have never met employees at a IT company with such high levels of expertise. Clearly why they have been in business for 30 years!! I recommend Systems Integration for small to large companies. They get to know your employees and business. I attached a picture of their security stack.

we hired systems integration after our previous IT company left us hanging when we had a ransomeware attack. We brought sii on board and they handled the rest. They also do not charge on going fees, instead everything fits inside our monthly package.
