Centralized security has protected APIs and optimized multi‑cloud traffic management
F5 Distributed Cloud Services has been used for two years for DDoS protection, and there is a particular feature called API protection. Within API protection, there is malicious user mitigation, which is one particular technology that has been implemented. This is a kind of advanced bot attack prevention. Malicious user mitigation is an AI/ML-based technology that was introduced by the F5 team, and this particular MUG protects rate limiting. If some users are having anomaly detection or someone is trying to do a bot attack, it will create a CAPTCHA challenge for that particular user alone and not for all users. For example, if someone is trying to act as a rogue, it will create a CAPTCHA challenge in the backend system on that particular system, so they cannot try again and again at the same time. It is for a concurrent session, and it will give the CAPTCHA challenge. This MUG, malicious user mitigation, prevents bot attacks. F5 Distributed Cloud Services includes the real-time intelligence feature, which helps with threat response strategies from a threat intelligence perspective. For example, if there are geo-restrictions or geo-based restrictions, sometimes people may come in through proxy-based servers, and it will prevent that. The load balancing feature optimizes application performance. Observability is the basic piece where F5 got introduced. This observability piece provides end-to-end visibility on the application performance. It gives complete end-to-end visibility across network latency and application performance issues. Sometimes when it is getting more than 200 pages, it throws errors such as 300, 400, or whatever has been configured, including 500 errors. F5 Distributed Cloud Services has helped improve traffic management efficiency. Most applications are hosted in the Check Point and F5 firewall, F5 web application firewall, where applications and traffic management can be accessed in a single dashboard. Automated threat detection is a basic feature of F5 Distributed Cloud Services meant for that purpose. There are two scenarios with automated threat detection, which is provided by F5. It is a completely machine learning solution that came from the bot defense, and it automatically protects against sophisticated attacks.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"F5 Distributed Cloud Services is the market leader in load balancers and manages traffic really well."
"F5 Distributed Cloud Services has positively impacted my organization from the security point of view, as all our applications are in a very stable, safe mode."
"Technical support from F5 is good compared to Cisco and HP."
"Overall, I would recommend it; it is very easy to use and effective, and you can immediately configure the policies and configurations you need, with results appearing in seconds."
"Elastic environments are the most valuable features because I can pull these apps and migrate the on-premises environment to the Distributed Cloud environment, and this capability is very strong and the security regarding the apps is really very powerful."
"I appreciate the UI of F5 Distributed Cloud Services and the backend cost, alongside the actual value proposition that they provide with the load balancer, which is excellent."
"F5 Distributed Cloud Services provides a single unified console for security operations, network operations, and DevOps across all environments."

"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."

Cons

"F5 Distributed Cloud Services still does not have the same flexibility as BIG-IP. It does not have iRules."
"For small players, it is completely not worth it."
"One area where F5 Distributed Cloud Services can be improved is in API security, which can be enhanced."
"The main issue is integration with other parts or products of F5, like on-premise WAF. There are some problems, mainly from the perspective of implementation and customer expectations, which sometimes differ from reality."
"I would evaluate F5 technical support as not particularly fast in replying, but it is effective."
"Last year there was a downtime of 30 minutes across the cloud distributed console, and that was the only impact observed."
"An improvement for F5 Distributed Cloud Services could be in usability."
"Sometimes this does not work and I go import them manually."
