Today’s organizations don’t operate behind a single “office firewall” anymore. Teams work from job sites, plants, home offices, and in the field—and that means the “network perimeter” is no longer a building. In many cases, the network is effectively the internet.
To reduce risk in this new reality, we’re implementing ThreatLocker® Network Control as a security upgrade for our clients across manufacturing, construction, and City/municipal departments.
This enhancement is designed to add a powerful, practical layer of protection that goes beyond usernames, passwords, and even MFA.
What is ThreatLocker Network Control?
ThreatLocker Network Control is a centrally managed endpoint firewall solution for workstations and servers. Instead of relying only on traditional perimeter firewalls and static rules, it allows us to control network traffic at the device level using custom-built policies.
In plain terms: it helps ensure that only approved, managed devices can communicate with your critical systems—and only in approved ways.
Why we’re implementing it (business-level reasons)
1) Protection even when credentials are compromised
Credentials are a common target. And while MFA is essential, attackers can sometimes still bypass it through token theft, social engineering, or other methods.
With Network Control, access can be tied to trusted devices—systems that are managed and authenticated.
So even if a hacker gained credentials and bypassed MFA, they still face a major barrier:
They would not be able to access protected network resources from an unknown device that doesn’t have ThreatLocker installed and authorized.
2) Reduced exposure of internal systems
Instead of leaving access broadly available “just in case,” ThreatLocker can use dynamic ACLs (access rules) to allow access when needed and reduce unnecessary exposure.
3) Strong fit for real-world operations (plants, job sites, City networks)
Manufacturing floors, construction environments, and municipal departments often have:
- A mix of older and newer systems
- Shared devices and segmented operational needs
- Field connectivity and remote access requirements
- High consequence of downtime
Network Control helps us apply consistent, centrally managed policies while supporting mobile and remote work.
How it works
- Centrally managed policies: We define what network communications are allowed for each device group (office users, engineering, servers, admin workstations, etc.).
- Granular control: Policies can be specific—down to which systems can communicate, over which ports/services, and under what conditions.
- Dynamic access (when appropriate): Access can be opened on-demand for approved devices and then automatically closed shortly after it’s no longer needed—helping reduce the window of exposure.
- Blocks unknown devices: Unapproved devices cannot connect to (or in many cases even see) protected access pathways.
What to expect from our rollout
We’ll implement this in a controlled, low-disruption way:
- Assessment & baseline
- Identify critical systems and required business applications
- Map essential traffic (what must communicate for operations to run)
- Pilot
- Start with a limited group to validate business workflows
- Phased rollout
- Expand in waves to reduce disruption and ensure stability
- Ongoing tuning
- Refine policies as systems and operational needs evolve
Our goal is improved security without slowing down production, field operations, or public services.
Short FAQ
Q: Is this replacing our firewall, VPN, or MFA?
A: No. This is an additional layer of security. It complements existing tools like perimeter firewalls, VPNs, and MFA by adding device- and policy-based network control.
Q: What problem does this solve that MFA doesn’t?
A: MFA verifies a user—Network Control helps verify the device and pathway. If credentials are stolen (even with MFA bypassed), an attacker may still be blocked because their device is not trusted/authorized.
Q: Will employees notice changes day-to-day?
A: In most cases, no. The rollout is designed to be smooth. If a workflow relies on a connection that should be allowed but isn’t yet in policy, we’ll adjust quickly as part of normal tuning.
Q: Does this impact plant systems, job-site connectivity, or City services?
A: The policies are designed around operational requirements. We baseline what must function, pilot carefully, and roll out in phases to prevent interruptions to critical services.
Q: What happens if a device is lost or stolen?
A: A lost/stolen device can be isolated quickly through policy. Network Control helps reduce what that device can reach, limiting potential impact.
Q: How does this reduce the risk of ransomware or internal spread?
A: By limiting unnecessary network paths, it can reduce lateral movement—making it harder for threats to move from one machine to another or reach high-value systems.
Bottom line
ThreatLocker Network Control strengthens security in a practical way: it helps ensure that access to key systems depends not just on “who you are” (credentials), but also on “what you’re connecting from” (a trusted, managed device) and “what you’re allowed to reach” (policy-controlled network traffic).
