Network and security

Firewalls and application delivery

Keep threats out, keep applications up, and control how people use the web. We implement (design, sizing, install, migration from old devices, testing) and manage (changes, firmware, monitoring, reviews).

What's included

  • Network firewalls: edge, between sites and inside the data center; rule clean-ups, intrusion prevention, application control, VPN, high-availability pairs
  • Load balancers: traffic spread across servers, health checks, SSL offload, failover between sites
  • Web application firewalls: protection of websites and APIs from common attacks, bots and abuse, tuned so real users aren't blocked
  • Web proxies: forward proxies for staff browsing with URL filtering and reports; reverse proxy managers that publish internal apps securely with automatic certificates
  • Quarterly rule and policy reviews with a written report

Questions

We have hundreds of old firewall rules. Can you clean them up?
Yes: we find unused and overlapping rules and remove them in stages, with your approval.
Will a WAF break our website?
We start in monitor mode, tune the rules, then switch to blocking.
Can you manage a firewall someone else installed?
Yes, after a review of its rules and firmware.
