Microsoft Defender for Office 365 and ThreatLocker Zero Trust Platform compete in the cybersecurity category, focusing on protective measures against unauthorized access and threats. While Microsoft Defender provides comprehensive integration and threat visibility within Office 365, ThreatLocker stands out for its precise application control and deny-by-default approach, making it particularly effective in security environments that require strict access management.
Features: Microsoft Defender for Office 365 includes features such as risk level notifications, email protection, and anti-phishing capabilities, which integrate seamlessly to deliver a unified threat management experience. ThreatLocker Zero Trust Platform offers application control, allow listing, and elevation control that enables real-time software management.
Room for Improvement: Microsoft Defender for Office 365 could improve its threat intelligence and reporting capabilities, as well as enhance compatibility with non-Microsoft file types. ThreatLocker could benefit from enhanced integration with SIEM tools and better automation, as well as user interface improvements to facilitate easier adoption.
Ease of Deployment and Customer Service: Microsoft Defender for Office 365 provides flexible deployment options in public, hybrid, and on-premises environments with reliable technical documentation and community support, though more complex issues can slow support response. ThreatLocker focuses on simplified setup and streamlined customer support, offering rapid integration and ongoing assistance as part of its pricing structure.
Pricing and ROI: Microsoft Defender for Office 365 is known for its comprehensive security features but carries a higher price tag, often challenging smaller budgets. Its ROI is reflected in reduced incident costs and operational efficiency. ThreatLocker's pricing structure is more flexible and cost-effective, appealing to small and medium businesses seeking controlled security solutions. Both offer a valuable return on investment, aligning with customer-specific security needs and budget considerations.
It has also decreased our time to detection and response by about 15 to 20 percent.
Overall, cost of owning and operating our system goes down.
It's hard to quantify the return on investment we've seen from Microsoft Defender for Office 365.
If something were to happen without ThreatLocker, the cost would be huge, and thus, having it is definitely worth it.
Based on what we use ThreatLocker Zero Trust Endpoint Protection Platform for with the same functionalities and packaging, it was around 13 or 14 hours.
We have the MDR package as well, and just knowing someone is watching those endpoints at 3:00 a.m. is a lifesaver that you cannot put a dollar figure on.
Over the past two years, there have been no critical problems.
we opened tickets, and they typically resolve them quickly.
With a subscription for Microsoft Defender for Office 365, it is an eight. Without it, it is a six.
They have been very responsive, helpful, and knowledgeable.
I would rate their customer support a ten out of ten.
Their support is world-class.
We have never faced scalability problems, and Microsoft manages it effectively.
Microsoft Defender for Office 365 scales transparently for us, as we grew from 1,000 users to 3,000 users, and we didn't notice much difference.
Microsoft Defender for Office 365 scales with the growing needs of my company well.
I started off with just the servers, and within a month and a half, I set up the entire company with ThreatLocker.
It seems to primarily operate on the endpoints rather than at a central location pushing out policies.
ThreatLocker Zero Trust Endpoint Protection Platform scales very smoothly with our growing needs.
I would rate the stability of Microsoft Defender for Office 365 as 10 over 10 because it's highly available, it works, and it does the job it is meant to do.
I have not experienced any downtime, crashes, or performance issues because of Defender.
The solution is stable, as we have been using it for the past two years.
For five years, we have not had a problem.
Once deployed, it downloads the policies locally, so even if the computer doesn't have internet, it doesn't matter.
It has been very stable, reliable, and accessible.
The main area for improvement is simplifying the implementation and rollout process.
Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published.
There is a different console for different things; I just want one consolidated console.
Controlling the cloud environment, not just endpoints, is crucial.
ThreatLocker Zero Trust Endpoint Protection Platform could improve by being a little more hands-off, perhaps by having a team inside ThreatLocker that does all the vetting of patches; having one person hired by ThreatLocker to check out patches means that a million other industries using ThreatLocker Zero Trust Endpoint Protection Platform do not have to vet the same patch, ultimately saving time and money around the world.
This feedback would help us understand what is learned in real-time, especially during a one-hour learning mode setup, ensuring we remain aware of potentially unnecessary learned items.
We've likely saved 30% of costs.
The standalone P2 can feel more expensive if enabled for all users, and the licensing might be somewhat confusing with terms like P1 versus P2 and feature dependency.
Money-wise, it is a part of the Office 365 suite, making it slightly more expensive compared to Trend Micro.
After conversations with other partners, it became clear we underpriced it initially, which caused most of our issues.
We are moving towards the Unified solution, where they basically bundle everything together, providing us better stability with the ability to bring in new product offerings without having to go back to the customer and say, 'This is going to cost you.'
Money is saved because it is not costly, and I would suggest it for other companies.
It ranks the threats and allows us to prioritize those hitting us the hardest, such as email threats.
It provides end-to-end visibility on email threats such as phishing, extending beyond Exchange Online Protection.
The value of the DLP feature is significant to us because we have internal data, sometimes sensitive, and the users may not always be aware of security and privacy, which might lead them to send out information mistakenly to external parties.
ThreatLocker Zero Trust Endpoint Protection Platform's ability to block access to unauthorized applications has been excellent.
It protects our customers.
The major benefit is fewer breaches overall, as nothing can be run without prior approval. This helps my company protect its data and secure itself effectively.
