What does network security include for a small business?
Network security is the set of controls that keep unwanted people and software off your business network: a properly configured firewall, secure remote access, updated devices, strong user and administrator access rules, and separation between systems that should not share a network.
TechCore provides network security and cybersecurity services for businesses in Middle Tennessee and Chattanooga. We review your firewall, users, devices and remote access, fix the most important gaps first and document who is responsible for what.

What we secure
Practical protection for your network
Security controls aligned with the way your business actually operates.
Firewall and perimeter review
We check firewall rules, firmware and settings so only the traffic you need gets in or out.
User and administrator access
Accounts reviewed so people have the access they need, admin rights are limited and old accounts are closed.
Device and endpoint protection
Updates and endpoint protection on computers and servers, with visibility into what is connected.
Secure remote access
VPN or other secure remote access for staff working from home or on the road.
Network segmentation
Guest Wi-Fi, business systems, phones and cameras separated so a problem in one area stays there.
Policies and responsibilities
Clear, written answers to who manages passwords, updates, backups and security alerts.
Why it matters
Most attacks go after the basics
Small businesses are usually hurt by common gaps, not sophisticated attacks: a firewall never updated, a former employee account still active, remote access left open or backups nobody has tested. Closing those gaps does most of the work.
TechCore handles the IT side of security. Physical security, including cameras and access control, is handled by our sister company Turner Security, and both run on your network, so one team can plan segmentation and access for all of it.

Common questions
Questions we hear a lot
How much do cybersecurity services cost for a small business?
It depends on the number of users, devices and locations and how much work your current setup needs. We start with a review and give you a written proposal so the cost is clear.
Is a firewall enough to protect my business?
No. A firewall is important, but most problems come through user accounts, outdated devices, email and remote access. Good network security covers all of those together.
What is network segmentation?
Segmentation means splitting your network into separate sections, such as guest Wi-Fi, business computers, phones and cameras. If one section has a problem, it is harder for it to spread to the others.
Do you set up secure remote access for employees?
Yes. We set up and support secure remote access so staff can reach business systems from home or on the road without leaving your network exposed.
Is cybersecurity included in managed IT?
Managed IT includes the security basics such as updates, endpoint protection and backup checks. Network security work like firewall reviews, segmentation and remote access is available as part of a plan or as a project.
Who secures our security cameras?
Cameras and access control are installed by our sister company Turner Security. TechCore makes sure they sit on the right part of your network with the right access rules.
We used Turner Security when our business transferred to a new location and they went above and beyond to make sure we were up and running for business as quickly as possible. Jamie, Mike, Reid, Nathan, Greg, TJ and Dan were all very polite, professional, and friendly. I highly recommend them for all your IT needs!

I am a manager for 4 locations of Express Employment Professionals and we've recently used TechCore for our phone service. Our installation was easy and fast! Jamie and Alex took extra care to make sure all of our needs were met in each office, they had everything installed and running on the same day and Alex has been incredibly helpful for any changes we've needed with staff changes. I would highly recommend TechCore's phone and networking service.
