UnderDefense and ThreatLocker Cyber Hero MDR are two competing solutions in the cybersecurity market. While UnderDefense is known for its pricing advantage and robust support, ThreatLocker Cyber Hero MDR distinguishes itself with a superior feature set, justifying its higher investment.
Features: UnderDefense offers anomaly detection, noise filtering, and comprehensive reporting, which collectively enhance threat detection and response. ThreatLocker Cyber Hero MDR features application whitelisting, extensive access control, and fast threat detection, which improve security granularity and proactive threat prevention.
Room for Improvement: UnderDefense could enhance predictive capabilities, offer more customizable dashboards, and provide better integration with third-party tools. ThreatLocker Cyber Hero MDR may benefit from simplified deployment, reducing false positives, and offering a more intuitive user interface.
Ease of Deployment and Customer Service: UnderDefense offers a straightforward deployment process with responsive support, ideal for immediate assistance. ThreatLocker Cyber Hero MDR, while requiring more deployment resources, provides exceptionally responsive customer service after reaching operational status.
Pricing and ROI: UnderDefense is more cost-effective, offering quicker ROI due to its competitive pricing model. ThreatLocker Cyber Hero MDR incurs a higher initial cost but offers long-term value by significantly enhancing security infrastructure and reducing security risks.
One customer who previously did not have anything like this mentioned having peace of mind, which is invaluable for a business owner.
It saves us from extensive remediation when a compromise occurs and aids in proactive measures before threats arise.
We now have enough to support technicians and bring someone else on board, which we could not do before because we were very inexpensive.
Log triage no longer takes up our security team's calendar, allowing those hours to go into platform architecture, our DRM protections, and proactive hardening.
Each alert comes with the caller, the endpoint, and the queries, so we do not dig through logs.
I have seen a return on investment, mainly in time and not having to build a team, as we did not need to hire a security team to get around-the-clock cloud coverage.
The senior team at ThreatLocker is also very accessible in case we need any help.
ThreatLocker's support and Cyber Heroes have the absolute best support in the industry, in my opinion, bar none.
The ThreatLocker team has been fantastic, assisting us at every step.
When we needed a baseline adjusted or a finding explained, we got a clear answer quickly.
I would rate the customer support on a scale of 1 to 10 as 10.
The customer support has been responsive and helpful.
I can onboard a new customer in no time, freeing up time for my team to onboard as many as needed without it taking too much time.
Scalability is great; I would rate it a ten out of ten.
It scales with you.
Our platform sees sharp spikes from bulk uploads and fast-spreading assets, and UnderDefense Agentic AI SOC handles them without needing us to resize or retune anything.
UnderDefense's scalability is good, as the same coverage applies as our cloud environment grows without us changing anything on our side.
Our traffic is high, and UnderDefense handles it without us changing anything.
What's been wonderful about ThreatLocker is when we have found an issue and identified it, the entire team has taken those things seriously and gotten them remediated for us and our clients quickly, and more quickly than I've experienced with other vendors.
I would rate it around nine out of ten.
We use it every day and it has run steadily, including when our traffic is high.
It is preferred that everything is seen under one tool rather than multiple platforms requiring multiple logins.
The Cyber Hero Support is not as effective as it is portrayed.
From an MDR perspective, the solution can have the ability to ingest logs from other sources, such as M365, firewalls, external sources, and even cloud SaaS-based platforms.
It is worth it for accurate triage later, but a template for common upload patterns will shorten that time.
The setup and daily use have both been smooth.
Showing the customer name in the alert would help.
Pricing is a bit high, with a minimum of 50 devices.
We would have been one of the biggest partners in Ireland, so we got pretty good pricing at the start, and it is still competitive.
We have an essential users package where we charge per head, and then we have an advanced security offering that we charge per head, and we've baked ThreatLocker into that advanced offering for our clients.
licensing was clear from the start, giving me good value for the price
Compared with building the same coverage in-house, it is a much lower cost and did not require us to hire.
Pricing was fair for what we get, setup was easy and took very little of our time, and the licensing was clear from the start, enabling us to see good value for the price.
We've seen an 80% to 90% improvement in remediation.
There is a tremendous amount that is helpful, such as their recording, watching the systems, locking down the systems, and their training.
When the update rolled out for version 18, it was able to catch a 3CX Supply Chain attack where a client had downloaded a DLL file that was trying to steal the authenticated Office 365 or authenticated G Suite tokens.
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.
It has full-time support 24/7 with proactive reports, and monitoring runs around the clock.
The sorting signals and clear reports help my team day-to-day because 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.
