Quick IT Tips
Practical advice for Greenfield businesses — whether you work with us or not.
- •Check your Greenfield office firewall firmware version today. If it has not been updated in the past 90 days, you are running with known vulnerabilities that have already been publicly disclosed to attackers.
- •If your guest Wi-Fi network can reach your internal servers or workstations, you have a segmentation problem. Test this by connecting a personal phone to guest Wi-Fi and trying to ping an internal IP address. If it responds, call us.
- •Greenfield businesses with multiple internet connections should configure automatic failover so an ISP outage does not shut down operations. If your internet goes out and you have a second connection sitting idle, that is a configuration problem — not a hardware problem.
- •Review the devices connected to your Greenfield office network monthly. Unknown or unauthorized devices are one of the most common indicators of a security issue — and most businesses have no idea what is actually on their network.
- •If your Greenfield business uses IoT devices — security cameras, smart thermostats, badge readers — make sure they are on an isolated network segment. IoT devices are notoriously insecure and are a common entry point for attackers to reach your business network.
What Our Clients Say
“Powerful IT Systems handles all our IT and are great to work with. Anything we need, they help out with pretty much immediately or same day if it can be handled remotely. They are also available for us at odd hours like when we have questions on weekends. Working with Powerful IT Systems has really felt like having an internal IT person without having to add another person to my payroll! Couldn’t recommend more.”
“Regularly checks in. Responds quickly.”
“Went BEYOND my expectations!!!! I called Powerful IT to see if my PC could be tuned up. It was older and running very slowly. Powerful IT Systems remoted into my system and looked every thing over. He then explained to me why my PC hardware was just not able to keep up anymore. More importantly, the prospect of trying to figure out what to replace it with was not something I looked forward to. Powerful IT Systems and I hopped on a major retailer website and he patiently walked me through several options until we settled on one that would work well for me and at a price-point I could afford. I was so relieved! I tried to pay Powerful IT Systems for his assistance but he refused saying he didn’t fix anything. I am extremely grateful for his time, expertise and guidance. I will definitely contact Powerful IT the next time I have an issue and highly recommend Powerful IT Systems to all my friends!”
