Program Manager at a outsourcing company with 51-200 employees
Effective threat protection with room for cost and usability improvements
There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

Improves decision-making with clear verdict explanations and works well across multiple environments
I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. 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. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of this solution are its ease of use and operation efficiency."
"The most valuable aspect for me is the user-friendly interface."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"The most valuable features of the solution are the antivirus and child protection features."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"The password thing is very good, and the overall URL protection."
"I would recommend it to others as it's easy to use."
"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"Since I have been using Sublime Security personally, I have noticed specific improvements like fewer spam emails and improved detection, which saves me time."
"This is why it provides absolute value; it adds a smarter layer that catches anything missed by Microsoft 365 or Google Workspace protection, as attackers can breach those systems easily using flexible detection logic that security teams can quickly customize."
"Sublime Security has positively impacted our organization by allowing us to do much less manual phishing detection and email detection, and now we can automate a lot of that, freeing up a lot of our security team to do other work."
"I like its ability to detect and block."
"Overall, the auditability and the ability to evaluate the information in Sublime through various mechanisms made me very comfortable with setting these capabilities to auto-remediation."
"Sublime Security has positively impacted my organization by helping our team reduce manual email triage and respond to phishing and BEC threats faster."
"Sublime Security has improved our email threat detection and response by helping us identify phishing and Business Email Compromise campaigns faster, investigate related emails, and automate remediation, which has reduced our manual effort and improved our response time."
 

Cons

"When I do a configuration, I do not know what implication it will have downstream."
"The customer support of the product is an area with shortcomings where improvements are required."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"I believe the absence of a procedure is the main issue."
"There is room for improvement in terms of the pricing."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"To improve Sublime Security, I think the learning curve is the primary concern; it is powerful, but it is not plug and play."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
"I would say there are very minimal changes needed regarding Sublime Security; for first-time users, it can be difficult knowing how to write the tool."
"There have been occasions where we would have liked a faster response, but the overall experience has been positive."
"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."
"Sublime Security could be improved by enabling more integration, better customization of alerts, and more detailed reporting."
"I believe the main areas for improvement for Sublime Security are ease of onboarding and learning, as the platform has many powerful capabilities, making it take some time for new analysts to become comfortable with all the features and detection logic."
 

Pricing and Cost Advice

"Personal computer licenses can be expensive if you were to scale the solution extensively. However, large companies will most likely use Endpoint solutions and not this one."
"I would rate the pricing a seven out of ten, with ten being very expensive and one being cheap. It's neither too cheap nor too expensive."
"I am okay with the pricing."
"I rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."
"It is expensive."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
