- Monitors network activity for unusual patterns or potential threats.
- Automatically responds to incidents, reducing response times.
Use Case:
An e-commerce company can use DNA Center to detect and mitigate DDoS attacks, ensuring uninterrupted service.
5. Endpoint Protection
What It Does:
The Catalyst 9300 works with Cisco Secure Endpoint to protect devices connected to the network.
How It Enhances Security:
- Identifies and blocks malicious files before they can cause damage.
- Provides visibility into endpoint activity, aiding in threat investigation.
Use Case:
A remote workforce can connect securely to the corporate network, reducing risks associated with personal devices.
6. Advanced Firewall Integration
What It Does:
The Catalyst 9300 integrates with Cisco’s advanced firewalls, enhancing perimeter security.
