Check Point Harmony Email & Collaboration and Sublime Security are both prominent products in the email security category. Check Point Harmony seems to hold an advantage in seamless integration with Microsoft's security systems and AI-driven threat intelligence, whereas Sublime Security excels in advanced threat detection with customizable rules.
Features: Check Point Harmony Email & Collaboration provides a robust security portfolio with AI-driven threat intelligence, seamless integration with Microsoft services, and strong phishing protection across collaborative environments. Sublime Security offers advanced phishing detection, deep email and header analysis, and customizable security rules for nuanced threat responses.
Room for Improvement: Check Point Harmony could improve by expanding integration with email services beyond Office 365 and Google Suite, and enhancing dashboard functionalities for better user experience. Sublime Security may need to focus on improving user training and threat explanation capabilities and enhance deployment customization and interface intuitiveness.
Ease of Deployment and Customer Service: Check Point Harmony supports hybrid and public cloud environments but has a complex setup process. Sublime Security focuses on public cloud integration, offering ease of platform integration. Customer support for Harmony varies, whereas Sublime users report good support but need better deployment assistance.
Pricing and ROI: Check Point Harmony Email & Collaboration is a premium offering with reports of significant ROI, due to reduced threat incidents. Sublime Security offers competitive, flexible pricing, particularly appealing to smaller organizations while delivering excellent threat detection functionality.
The time saved during investigations is significant due to the neat dashboard that organizes everything related to alerts.
We have gone from three to four successful phishing attacks every year to a maximum of one.
There has been a 70% decrease in phishing emails and data breaches since implementing Check Point Harmony Email Security.
Importantly, we didn’t need to hire any additional staff; we were able to absorb this responsibility using our existing team.
Their technical support is proficient at resolving issues within their scope, providing excellent problem-solving assistance and guidance.
We opted for the 24/7 premium support, which is very responsive and quick whenever we have configuration challenges or other inquiries.
We understand that with respect to SLA, but we expect they can go beyond SLA and provide quick support for the client.
We were able to get in touch with the person who constructed the LLM and its agentic aspects relatively quickly to address our questions.
I would rate the scalability of Check Point Harmony Email and Collaboration as nine out of ten, indicating high scalability.
If I want to scale this product to 2,000 users or 5,000 users, it can scale within no time, so that is not an issue.
Scalability is limited, being only integrated with Microsoft Office 365 and G Suite at present.
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.
The platform is very stable; we have not encountered any downtime or stability-related issues.
Over these eighteen months I have been working with the product, it has been very stable, and I would recommend it to most of my peers who have issues related to the email security piece.
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.
Updates based on AI and reduced administrative overhead by adding or bulk adding new users, along with graphical enhancements to the GUI, would also be beneficial.
Enhancing reporting capabilities with customizable and advanced analytics features would greatly improve our ability to detect trends and proactively address emerging threats.
The current system, being tied directly to the mailbox instead of requiring MX record verification, allows new mailboxes to function immediately after Microsoft activation.
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.
One breach could potentially put a small company out of business, so having a tool such as this might save them from that fate.
Pricing is a bit expensive, but it is worth it considering the features that Check Point provides.
I consider the pricing to be a bit expensive, similar to other solutions.
The pricing is lower compared to what I used before.
It's competitive with its peers, especially for the number of mailboxes we have.
I haven't had any users accidentally click on something problematic since implementing the product, which speaks to its efficacy.
For us, I prefer Check Point before Palo Alto and before other brands because Check Point is most effective in attack mitigation and attack detection.
The most valuable feature is spam detection and phishing site prevention, which Microsoft couldn't catch, yet Check Point does.
This level of detail is essential for analysts and anyone conducting evaluations, as it helps them understand the specific circumstances of their environment.
It adds a smarter layer that catches anything missed by Microsoft 365 or Google Workspace protection.
