Using this solution provides financial benefits by securing from server attacks, which offers indirect savings.
Systems Specialist/ Administrator at ALFA International Company Limited.
Importantly, we didn’t need to hire any additional staff; we were able to absorb this responsibility using our existing team.
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.

The challenge lies in waiting for a response after logging a ticket.

We were able to get in touch with the person who constructed the LLM and its agentic aspects relatively quickly to address our questions.
Manager Security Operations Center at a educational organization with 10,001+ employees
They're able to understand the context of an incident rather than just treating it as a generic support ticket.

Network & Security Section Head/Digital Transformation at a government with 201-500 employees
Since it's cloud-based, it expands easily.
Head of Technology Operations at Pobl Group
There is still a gap in terms of storage, and we are trying to figure out how to increase that capacity for regulated environments, which require data retention for 5 to 6 years.
Technical Consultant - Unix Platform Services at BITS AND BYTE IT CONSULTING PVT LTD
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.

Room For Improvement

Darktrace needs a simpler interface, reduced false positives, refined reporting, better integration, flexible pricing, and improved support.
Sublime Security should enhance user onboarding, integration, customization, and reporting while addressing pricing and reducing false positives.
There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market.
Solution Architect at a tech services company with 51-200 employees
They say they can integrate with most firewalls, but when we did an integration with Meraki MX firewalls, that integration didn't work and still doesn't work to this day.
Security Analyst at a healthcare company with 10,001+ employees
We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.
Technical Consultant - Unix Platform Services at BITS AND BYTE IT CONSULTING PVT LTD
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.

I can also understand why some people might say it's expensive.

It's competitive with its peers, especially for the number of mailboxes we have.

Security Information & Incident Analyst at a financial services firm with 1,001-5,000 employees
If I am in a data center where I don't have layer two, it becomes an issue because the autonomous response is reliant on sending spoofed TCP resets to my core switch to block traffic, which is a major issue.
Security Analyst at a healthcare company with 10,001+ employees
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

Featured Reviews

Pasan Jayarathna - PeerSpot reviewer
Network Security Engineer at Cyberwell Solution
Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

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.
