Room For Improvement

OpenText Enterprise Security Manager needs user interface upgrades, better integration, improved documentation, and enhancements in analytics and scalability.
Sumo Logic Security needs improved dashboards, better automation, enhanced APIs, and easier integration to compete effectively with rivals.
The integration aspect of ArcSight Enterprise Security Manager (ESM) needs improvement.
Senior Security Engineer at Valuepoint Systems
I would also appreciate the AWS automation integrations to be more secure because currently, they are using access keys, which involves a user rather than roles, which is the security best practice recommended by AWS.
Senior Security Analyst at City Electric Supply Company
This can lead to alerts that are collections of disjointed signals that sometimes make no sense and lack real context; this simplistic approach makes it hard to find coherent stories during investigations.
CSO at Altera
This is crucial to sell to the government and financial sectors as they require data retention within each country.
Deputy Country Manager at PT Securite Asia Indonesia (ABP Securite)

OpenText Enterprise Security Manager is costly but offers robust features and scalability, with possible discounts and cost management strategies.
Sumo Logic's pricing is seen as high yet valuable, competitive, and convenient via AWS, though scaling may be costly.

Senior Security Engineer at Valuepoint Systems
This makes it more cost-effective because other solutions often include a third element in their pricing.

ArcSight offers advanced threat detection, robust integration, customizable dashboards, and automates event correlation for efficient security operations.
Sumo Logic Security enhances efficiency with customizable features, AI-driven analytics, and responsive tools for streamlined troubleshooting and threat management.

We are able to save time on fewer alerts because we are able to perform tuning on the logs to be able to only get relevant security-related incidents.
Senior Security Analyst at City Electric Supply Company
The features I find most useful in Sumo Logic Security are the ease of implementation and connectors; they have a very easy connection and many connectors to important systems, making it very easy to implement and fast to start running in production.
CSO at Altera
If we cannot find the data in other tools, like email security or NDR, we can fetch those logs in the Log Analytics platform of Sumo Logic.

Senior Security Engineer at Valuepoint Systems
Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.

Security insights have enabled faster incident response and streamlined cross-team collaboration
To improve Sumo Logic Security, I would appreciate the tool being easier to use from a search perspective. For example, we have a few teams that want to use the tool itself, but they are not as savvy when it comes to creating searches from the core platform. I understand that Mobot has come out and is in the works, and it really does assist non-savvy users when it comes to querying the platform. As far as that is concerned, I wish that could be improved a bit more, but I do know that that is in the works. I would add that I wish for improved documentation. For example, we are using Sumo Playbooks and automation integrations along with that, but I have found that there has been a lack of documentation, very little to none at all when it comes to that. With regards to automation integrations as well, there are very few details included in them. I would also appreciate the AWS automation integrations to be more secure because currently, they are using access keys, which involves a user rather than roles, which is the security best practice recommended by AWS. I chose eight out of ten because to make it a nine or ten, I would lean heavily on the documentation. A lot of the times when we get around to configuring things such as playbooks or trying to understand playbooks, what I found was that documentation sometimes is not up to date or documentation is lacking. There are instances also where some security best practices are not being followed. So, if we are able to set up an integration that is not only secure, following security best practices, and has complete documentation, I believe it would alleviate the issue of having to go back and forth with support to check the documentation and things of that nature. My impression of the built-in threat intelligence feature in Sumo Logic Security is that it is comprehensive, but I would say that it could do a little bit better. For example, we have the TAXI feeds, which is STIX and TAXI integrated into the core platform, but the issue I am running into is that I am able to use that feed into a CSE alert; however, I am not able to see the contents of that feed. If I integrate CISA, which we do have integrated, I cannot see what IOCs are in that feed in the core platform, and I hope that is the case because, in order for us to better tune our alerts, we need to be able to see what is in the contents of that threat intelligence feed.
