Featured Reviews

Jörg Köhler - PeerSpot reviewer
Owner at AvalisNT AG
Efficient email security and link scanning streamline network protection
One area for improvement is the user-friendliness of the UI. It is not intuitive to manage policies as I have to go through several pages to find necessary information. Additionally, the profile management for scanning and protection profiles is clumsy and could be more straightforward. There should be some simplification in changing profiles due to performance issues.
Ivan Voitovych - PeerSpot reviewer
Founder at Urlicer
AI-driven SOC triage has transformed threat monitoring and keeps our security work focused
The best features UnderDefense offers include mostly triage in-context signals read together across my stack, where one finding replaces many separate checks. A good thing too is its false positive suppression, as I do not get false notifications. Normal activity such as traffic spikes during customer events is recognized and documented, and only the unusual cases reach me. It has full-time support 24/7 with proactive reports, and monitoring runs around the clock. Reports and alerts come to me without even noticing or asking, so it is very useful. My team sees what happened without having to chase it. I find the proactive reporting and 24/7 support to have definitely made a real difference. Proactive reports mean I hear about what happened without having to ask, so I know the state of things at the start of the day, and 24/7 support matters most for traffic spikes and other events outside busy working hours, as I get an answer when I need one without keeping someone on call just in case, saving me a lot of time. Together, they let my team stay on infrastructure work and step in only when a decision is needed. Regarding UnderDefense's AI capabilities, I think the governance and security is the best there is, as the decisions that matter stay with my team and each finding is documented, allowing me to review afterwards how a conclusion was reached. That control and traceability is what I need from AI in a security role. The accuracy and reliability of UnderDefense's AI output is accurate and steady, as findings have matched what I saw when I checked them, and the pattern assessments are consistent, especially during large traffic events or spikes, which is when I depend on them most. When a case needs judgment, the reasoning is there so I can confirm it myself.

Quotes from Members

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

Pros

"We find it extremely effective. We probably have over 500 endpoints, and we have not had any reports of viruses since we have installed it. It is very reliable."
"I would rate the stability a nine out of ten."
"The main thing I like about it is it's got all the features I need."
"The most valuable features include email security and web URL scanning, particularly the link scanning aspect."
"Bitdefender MDR's integration capabilities have been smooth, leveraging cloud-based and various threat intelligence feeds. Bitdefender's array of technologies, including remote mapping and machine learning, with numerous patents, ensures effective threat management."
"It's easy to use."
"A user cannot uninstall or disable the tool from their systems. It has ransomware blocking and zero-day threat protection. The tool also alerts us whenever a system or device has been compromised. It has a web control feature to manage website categories."
"I like the EDR feature."
"The linking, the filtering, and the readable reasoning each help on their own, but together, they allow a small security team to handle the volume our platform produces without losing sight of the cases that matter."
"UnderDefense Gen AI SOC flags behavior that breaks from an account's own baseline, lays out which signals triggered the alert and why it reads as different from normal activity, and helps our team decide within the same day whether we are seeing a legitimate big campaign push or a compromised login."
"Routine signals are handled and documented, and only cases that need a human decision reach my team, allowing engineers to spend their time on infrastructure hardening instead of log digging."
"UnderDefense groups it into one alert with the caller, the endpoint, and the usual pattern, which allows us to contact the customer the same day with facts in hand."
"Every morning we look at a short list of cases that matter instead of a long list of raw alerts, and each case comes with the full picture, so we can decide in a few minutes whether it needs action."
 

Cons

"For improvements, focusing on the commercial viability of markets like India could make it more accessible. The pricing structure, especially for price-sensitive markets like those in Asian countries."
"Integration capabilities are not as rich as other tools like CrowdStrike's. Bitdefender wasn't as feature-rich in that aspect."
"They can improve their support a little bit. We've had some issues with some of the installations in terms of getting the installation, configuration, and flows correct, and sometimes, their support is not as simple and easy to deal with as we'd like."
"We need more updates as there are always more threats coming."
"The lack of integration with Microsoft Outlook is a significant drawback."
"One area for improvement is the user-friendliness of the UI. It is not intuitive to manage policies as I have to go through several pages to find necessary information."
"They're doing a really good job. The throughput and the response time can always be better, but there's already a solution out there. It depends on how much and what tier you want to be a part of. The way they're designed is that if you pay for it, you can have a turnaround time in a very short amount of time. If you don't pay for it, your response time is going to be a little bit less. That can always be improved, no matter what tier you're on. It could be in terms of tech support, or it could also be things like getting the reports and getting the summary back from the labs. When something is detected, what did it all entail? There are a lot of those things. It's not all in one, but all of those are different branches."
"Bitdefender MDR consumes too many resources during scanning which further affects developers' productivity."
"UnderDefense could improve in onboarding, which takes some dedicated time because the baseline for our high volume upload events needs to be set up first."
 

Pricing and Cost Advice

"I know it is based on the volume and size and also on different multi-year agreements. There are different discounts applied, but I can't really speak about the specifics."
"I would rate the tool's pricing a four out of ten."
"Bitdefender fit well for customers with about 50 to 200 users. The price point is great, and you get a lot of bang for your buck."
"It varies based on the number of licenses."
"As far as pricing is concerned, I would rate them not expensive, not cheap."
