Security Features of the WatchGuard Firebox T125
With the promise of layered security, the T125 carries that same reliability that you’ll find in the entire WatchGuard firewalls lineup. A few highlights here include things like advanced traffic inspection, threat prevention, and app-level controls.
Moreover, the firewall also comes with stateful packet inspection, intrusion prevention, and antivirus protection. Essentially, your business network gets what it needs to detect and block threats before it wreaks havoc on your network. Tack on TLS decryption, flexible content filtering, and the rest of the security stack, and your network is always in good hands.
Advanced Threat Protection
The phrase advanced threat protection gets thrown around a lot in this industry, but it entails a lot more than it sounds. In the realm of firewall products, more specifically the T125, this means quite a bit, to be honest.
Here’s what advanced threat protection looks like with the T125:
- Tracks active network sessions to distinguish trusted and suspicious traffic
- Blocks known exploits and network-based attacks before they reach endpoints
- Provides built-in antivirus protection for malware detection
- Protects against DoS attacks
- Identifies malformed packets and blended threats targeting business networks
Overall, you shouldn’t have to worry much about evolving threats. If you ask me, the WatchGuard T125 offers much more than your standard entry level firewall.
TLS Decryption and Proxy Firewall
For those who aren’t already familiar, TLS decryption can work to inspect encrypted network traffic. Moreover, this improves visibility into HTTPS sessions that could potentially hide threats.
Below, you’ll find a few other core details you’ll want to know about:
- Proxy firewall functionality helps with deeper traffic inspection
- Applies app-layer security controls that go beyond basic packet filtering
- Comes with greater control over app-specific network traffic
- Improves threat detection through analyzing traffic at the application level
- Supports various email protocols like POP3S, SMTPS, and IMAPS
While TLS decryption isn’t necessarily rare among next-gen firewalls, it’s still crucial to understand. If you want true visibility across your network, TLS is a big part of the recipe, whether you’re a small or much larger organization.
Flexible Content Filtering and App Control
If you want safe web browsing for your entire workforce, then you’ll want to make use of content filtering. It’s also a helpful component to enforcing company-wide web access policies.
Here’s how content filtering and app control can benefit your operation:
- Restricts access to risky or inappropriate websites
- Provides app control across business networks
- Helps manage which apps can access your business network
- Reduces exposure to unsafe online content and services
- Supports productivity by limiting unnecessary internet usage
It’s pretty straightforward, and it’s a big help to companies that need to maintain security and compliance requirements. This isn’t just about preventing leisure time online, but maintaining operational security on a much, much deeper level.
