Sentiment score
4.5
Sublime Security reduces security risks and costs, enhances efficiency, and streamlines email investigations, improving organizational operations.

Manager Security Operations Center at a educational organization with 10,001+ employees
I estimate that we have improved our efficiency, especially for phishing campaigns where we can handle multiple similar emails together, which has reduced repetitive analyst work and improved our response time.
Soc Analyst at a manufacturing company with 10,001+ employees
I think the ROI for us is primarily in reduced security risk and reduced analyst time.

They're able to understand the context of an incident rather than just treating it as a generic support ticket.

Scalability Issues

Sentiment score
8.2
Avanan integrates with Office 365 and Google, praised for scalability, admin capabilities, and efficient email protection across diverse organizations.
Sentiment score
7.1
Sublime Security is highly scalable and resource-efficient, effectively handling large email volumes across Microsoft 365 and Google Workspace.
Despite nearly doubling the number of mailboxes and adding significantly more detection rules, the service remains just as fast as it was when we first implemented it.
Manager Security Operations Center at a educational organization with 10,001+ employees
Its scalability is also good, as it can scale with the number of protected mailboxes or users, or as email volume grows, supporting enterprise development across Microsoft 365 or Google Workspace.
Soc Analyst at a manufacturing company with 10,001+ employees
We have a fairly large Microsoft 365 environment and haven't had any problems with the platform keeping up with our email volume.
Technical Lead at a consultancy with 11-50 employees
 

Stability Issues

Sentiment score
8.5
Avanan is highly praised for its stability, efficiency, security, minimal maintenance, seamless Microsoft 365 integration, and reliable AI-based scanning.
Sentiment score
8.7
Sublime Security offers stable, reliable email security with quick performance, efficient threat detection, and no downtime or crashes.
Sublime Security acted quickly; once Microsoft alerted Outlook about the incoming email, Sublime Security managed to pull it from the stream before it had a chance to appear in the user's inbox.

Room For Improvement

Users feel Avanan needs improvements in Active Directory dependency, email quarantining, AI logic, training, UI, performance, pricing, mobile app, and integrations.
Sublime Security should enhance user onboarding, integration, customization, and reporting while addressing pricing and reducing false positives.
Often I have to prepare reports for our CEOs, and they want it in a less technical way, a simpler view of things such as threats blocked, incidents investigated, and overall risk reduction.
Technical Lead at a consultancy with 11-50 employees
Regarding needed improvements, I think the documentation is generally useful, but I would appreciate more beginner-friendly guidance and practical SOC examples, particularly around setting up detections, tuning rules, and integrating Sublime Security with SIEM and SOAR platforms.
Soc Analyst at a manufacturing company with 10,001+ employees
Sublime Security could be improved by enabling more integration, better customization of alerts, and more detailed reporting.

Setup Cost

Avanan provides flexible pricing for Office 365, with straightforward setup and costs between $4 to $8 per user.
Sublime Security's pricing is higher but justified by effective threat prevention, with competitive AWS Marketplace setup and licensing.
I can also understand why some people might say it's expensive.
Technical Lead at a consultancy with 11-50 employees
It's competitive with its peers, especially for the number of mailboxes we have.

Valuable Features

Avanan provides advanced malware and phishing detection, 24/7 cloud protection, easy integration with Microsoft 365, and ensures secure communications.
Sublime Security offers advanced phishing detection, AI analysis, and automated threat responses, enhancing email security and reducing manual efforts.
This level of detail is essential for analysts and anyone conducting evaluations, as it helps them understand the specific circumstances of their environment.
Manager Security Operations Center at a educational organization with 10,001+ employees
It adds a smarter layer that catches anything missed by Microsoft 365 or Google Workspace protection.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
I'd say the best features Sublime Security offers are the threat detection and investigation capabilities, which are probably the most valuable part for us.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Email defenses have reduced manual phishing work and now give clear visibility into threats
I'd say the best features Sublime Security offers are the threat detection and investigation capabilities, which are probably the most valuable part for us. I particularly appreciate the visibility into the email activity and the ability to investigate suspicious messages and understand why something was flagged. I'd say the protection against more sophisticated phishing and business email compromise attacks is also important. Those are difficult to deal with because they don't always contain obvious malware. The investigation capabilities of Sublime Security stand out because they surface themselves in a very nice, obvious way. So when we are investigating, they're just easy to spot and easy to identify. The UI is very clear for us, and overall it's just what we would expect. Regarding Sublime Security's AI capabilities, I think it's honestly pretty good. I haven't had any issues with either the governance side or the security side. I think Sublime Security has been very accurate. For us, it's certainly stopped a lot of the manual investigation that we often do for phishing emails or malicious emails. Occasionally, it does give us false positives, but that's just a five-minute review of something, so it still cuts a lot of time down.
