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.

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.

We have a fairly large Microsoft 365 environment and haven't had any problems with the platform keeping up with our email volume.

Room For Improvement

IRONSCALES needs better Google Suite integration, intuitive UI, enhanced features, multilingual support, and improved email detection accuracy.
Sublime Security should enhance user onboarding, integration, customization, and reporting while addressing pricing and reducing false positives.
If there were clickable drill downs on specific users or specific correspondence to relate them to certain types of mails, that would be beneficial.

Having a more user-friendly UI would make it easier to identify features and options when using the tool.
SOC LEAD at a tech vendor with 10,001+ employees
Though this isn't problematic for our users, the content could be updated more frequently.
Systems Engineer at a tech services company with 10,001+ employees
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
While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value.
Manager Security Operations Center at a educational organization with 10,001+ employees
One breach could potentially put a small company out of business, so having a tool such as this might save them from that fate.

Setup Cost

IRONSCALES offers valuable email security with high pricing, involving annual licensing and fees, considered worthwhile for phishing prevention.
Sublime Security's pricing is higher but justified by effective threat prevention, with competitive AWS Marketplace setup and licensing.

Featured Reviews

reviewer2770017 - PeerSpot reviewer
Email Security Analyst at a computer software company with 51-200 employees
Has improved threat analysis by providing clear email correspondence history and reporting tools
The best features IRONSCALES offers are the investigation tabs, headers, and correspondence history, which stand out the most for me. The investigation tabs are valuable for my work because reporting goes a long way in terms of playbooks and having a full investigation. The investigation tab knows exactly how to put the information in a way that makes it very easy for reports to get done fast. Security awareness training is a big part of IRONSCALES. The platform offers a broad spectrum in terms of what campaigns can be run for security awareness for users as well as reporting back on how users interact with their mails and understanding where the vulnerabilities lie. IRONSCALES has positively impacted my organization by making email security simple in terms of controlling mails, understanding where the threats are, and protecting the organization itself.

Technical Lead at a consultancy with 11-50 employees
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.
