Pros & Cons from Real Users

Pros

  • We acquired the solution for our deployment in our branches with a goal of load balancing and QoS features, I have to say that we were impressed by the quality of the solution and the professionalism of the support team. I highly recommend CacheGuard.
  • Hello! I just wanted to drop a quick note to let you know that I've been really impressed with CacheGuard. The service has been incredibly user-friendly and has exceeded my expectations in terms of simplicity and effectiveness.

Cons

  • We have the solution in production and so far so good.
  • I also wanted to express my sincere appreciation to the CacheGuard support team. They've been fantastic in providing prompt and helpful assistance whenever I've needed it. Thank You.

Pros & Cons from Real Users

Pros

  • AI enabled first-seen ability to scan a website in real-time for unknown websites; great filtering and extremely fast resolver. Offers DNS relay servers with DoT. DoH is now offered for routers. Customer support representatives are very friendly, engaged, and extremely helpful. They work until there is a resolution. DNS relay server app was recently upgraded to include management ability, which has helped tremendously instead of needing to self-install.
  • + Easy to use + One-click CIPA compliance + Users can submit unblock requests directly from the block page + Changes to block lists take effect instantly + The interface is fast and intuitive + Excellent support

Cons

  • Has fallen behind other resolvers with filters. No geographical blocking (only top-level domains; cannot block by regional IPs). DNSSEC support is limited (they actively discourage it). DNSSEC support is non-existent for DoH resolver. Many filter lists do not compare to competitors. IPv6 support is behind other resolvers. NAT addresses only allow you to specify an v6 or v4 address -- not both, which severely limits ability to use non-encrypted resolvers. No v6 support for the DNS relay server software, but they are supposedly developing it.
  • We'd like to have different filtering policies based on which VLAN the user is on. This can be done but it's a bit complex if you use Active Directory integrated DNS as we do.
