TheGartman controls network communications. The antivirus analyzes files and processes on equipment. They protect different surfaces.
In brief….A correct defense combines both: the19th reduces the allowed communications and the virus protects the terminal from the threats that reach it.

Key points…
- Inward and outward filtering
- Cross-area segmentation and control
- Log-in
Solution B.
Antivirus
The antivirus detects and blocks malware on the post or server.
Key points…
- File and Process Analysis
- Quarantine and local remediation
- Protection against numerous threats executed on the terminal
Comparative table….
| Criterion…. | Firewall | Antivirus |
|---|---|---|
| Location | Network, host or both | Mainly host |
| Object analysed | Flows and connections | Files, Memory and Process |
| Example | Blocking a port from the Internet | Blocking a downloaded Trojan |
| Complementarity | N, stop everything,, authorized to move | Do not replace network segmentation |
Choose Firewall if…
You must limit communications between Internet, users, servers and VLANs.
Choose Antivirus if…
You need to detect malicious files and behaviors executed on the posts.
Key takeaways
A correct defense combines both: the19th reduces the allowed communications and the virus protects the terminal from the threats that reach it.
