How a firewall protects your IT infrastructure
Firewalls block unwanted traffic from reaching your network – but how do they know which traffic is unwanted? With a managed firewall service, you get the benefit of expert oversight.
Proactively taking action
Security specialists study your network traffic, learn what is normal, and act on anything out of the ordinary. A Managed Firewall service helps to:
- Protect against cybercrime - A managed firewall helps business owners lower their risk of a breach.
- Meet compliance requirements - As threats grow, so do regulatory requirements. From HIPAA and GDPR to Sarbanes Oxley, make sure you’re compliant by using our managed firewall services.
- Ease burden of monitoring - Continuous monitoring is a drain on resources. Appointing a managed firewall service saves time and money.
