We had already been using Cloudflare as our CDN, so it was a natural first choice. We however passed because it didn't offer deep behavior analytics. We ran simulations with scripted bots mimicking human cursor movements and variable delays. It missed about 30% of them. That …
Clodflare bot management was our other obvious option for us. We tested it on a staging version of our RFQ platform. It was great for broad traffic filtering but had a hard time with nuanced differences between real subcontractors and low volume bots mimickingt human input …
I wasn't here at the time when the company compared different vulnerability management platforms so I'm not sure on the reasoning and difference between the 2. It could be that the team went through different choices and found Vulcan to be the best fit. It's hard for me to say …
My role is not in charge of selecting more services or products like Vulcan. I just use them as part of my daily responsibilities. Maybe other roles can give more feedback about this.
Vulcan Cyber has a more mature platform catered for enterprise customers compared to Nucleus. The very close support and attention to detail of the Vulcan sales and technical team also helped in answering any possible question we had about the platform or take note of our …
Vulcan was easier to implement with our existing Security environment. The UX and UI were more intuitive and user-friendly. While SOAR is a super solid product, for our business Vulcan made more sense. It was more of a natural fit for a rapidly-expanding company in a …
I'd strongly recommend it, but with a few caveats depending on how mature the team is with behavioral based security tools. One of our fintech clients was getting hit with low volume, widely spread login attempts, below our rate limiting thresholds. F5 Distributed Cloud Bot Defense was able to flag abnormal input timings, inconsistent device fingerprinting and high entropy in field population behavior. You can only imagine the wave of downstream account lockouts this saved the client. On the other end we had a client with a real time trading platform using Graphql over websockets. F5 Distributed Cloud Bot Defense wasn't able to tap into that stream natively. we had to reverse engineer a proxy layer to inspect events. It worked but it was clunky and not officially supported
We use Vulcan Cyber to help with the technical debt accrued over time with systems that were not maintained as well as they should be. To combat this, we use the campaign feature to keep a running tab on every system to ensure it is brought up to standards and maintained.
Regularly analyze traffic patterns and bot activity. Use the insights provided by the platform to refine rules and policies.
Configure rules to specify acceptable behavior for user interactions and alter sensitivity levels as appropriate to reduce false positives.
Integrate F5 Bot Defense into our existing security stack, which may include WAFs (Web Application Firewalls) and SIEM (Security Information and Event Management) solutions.
Official support can sometimes take time to reach the right people. However, once you are in contact with the appropriate experts, the support is excellent, as F5 staff are true specialists. On the other hand, we always receive prompt assistance from our local sales team, who typically help us connect with the right people quickly.
Implementation of Distributed Cloud is accomplished a few different ways, it would pay to meet with the F5 team and map out your implementation prior to acquisition to make sure you Infrastructure and Operations teams are aligned to the approach and requirements.
Clodflare bot management was our other obvious option for us. We tested it on a staging version of our RFQ platform. It was great for broad traffic filtering but had a hard time with nuanced differences between real subcontractors and low volume bots mimickingt human input whereas that's where F5 Distributed Cloud Bot Defense thrived
Vulcan was easier to implement with our existing Security environment. The UX and UI were more intuitive and user-friendly. While SOAR is a super solid product, for our business Vulcan made more sense. It was more of a natural fit for a rapidly-expanding company in a hyper-growth phase using Edge technology.
We experience large web/data scraping attack campaigns and F5 Distributed Cloud Bot Defense over the years has helped mitigate these for us and significantly reducing load off of our origin servers.
Also, we experience many large Credential Stuffing attacks and F5 Distributed Cloud Bot Defense helps us stop these attacks and protects our customers.
Allows much better prioritizing of which assets are most vulnerable
Allow a better understanding of what assets are actually under real threat vs. what is assumed to be vulnerable, but the real world fact is the system would be hard to reach internally, so it's not as vulnerable.
