Room For Improvement

Graylog Enterprise requires scalability, cost efficiency, and ease of use while enhancing alarms, AI capabilities, and integration with systems.
Users urge improvements in interface usability, automation, integration, support, AI capabilities, pricing, and visualization for Sumo Logic Security.
Mainly, it's about integrations: being able to parse different sources and output to different systems easier.
Head of Cyber Security & CTO at a tech services company with 51-200 employees
I understand that Graylog Enterprise is not a SIEM; it is a log management tool. However, it was able to meet my needs for security log monitoring specifically.
Specialist at Vihira Gets
Writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work.
Security Analyst at Netsharqs cybersecurity GmbH
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
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
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk.
Soc Analyst at a outsourcing company with 5,001-10,000 employees
 

Setup Cost

Graylog provides a free version for small needs and a cost-effective Enterprise version for larger, scalable requirements.
Sumo Logic Security offers mid-range pricing, balancing cost and functionality, with convenience through AWS Marketplace but increasing costs with usage.
It costs approximately $50,000 or $60,000 for 100 GB a day.
Head of Cyber Security & CTO at a tech services company with 51-200 employees
Regarding my experience with the price, configuration cost, and licensing of Graylog Enterprise, I consider that the cost-benefit ratio is very good when compared.
Desenvolvedor Javascript Junior at a educational organization with 10,001+ employees
I worked in the SOC environment focusing more on analyzing alerts, but I was able to understand the configurations well, including setting up use cases and automations.
Consultor De Informação Plena at Protivity Brasil
This makes it more cost-effective because other solutions often include a third element in their pricing.
Deputy Country Manager at PT Securite Asia Indonesia (ABP Securite)
From one to ten, where one is cheap and ten is expensive, I would put Sumo Logic Security at a seven.
CISO / Founder / GRC at VINCTA BV
If you go to the well-known vendors such as Azure Sentinel or other tools like Splunk, you are going to find them costly since they are well-known and they have much more integration compared to Sumo Logic Security.
Security Analyst at a tech vendor with 10,001+ employees
 

Valuable Features

Graylog Enterprise offers advanced log management, real-time access, and integrations, enhancing data analysis, monitoring, and user experience efficiency.
Sumo Logic Security offers comprehensive log aggregation, AI analytics, and scalability, enhancing detection, response, and operational efficiency.
The Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm.
Head of Cyber Security & CTO at a tech services company with 51-200 employees
The best feature of Graylog Enterprise is its high-performance search engine that provides fast, flexible, and scalable analysis of machine data or pod data.
Junior Dev Ops Engineer at a consultancy with 11-50 employees
Monitoring improved by up to 80 percent because of having all the logs centralized.
Platform Engineering at a comms service provider with 1,001-5,000 employees
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
They 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 or security relevant incidents.
Senior Security Analyst at City Electric Supply Company
My SOC analysts were crushed under Splunk, but Sumo has actually eased the workload and made it tolerable for three people.

Gabriel R. Sousa - PeerSpot reviewer
Consultor De Informação Plena at Protivity Brasil
Centralized logging has provided full security visibility and supports faster incident investigations
I think one of the positive points Graylog Enterprise offers is this centralization of logs, which greatly facilitates investigation work. Another point is its ability to perform searches, apply filters, and run queries so that you can look for a specific event, user, or IP. I think Graylog Enterprise brought efficiency gains because when you run a search or do some research, you can save it, so you do not need to enter the query again; you just retrieve what is already saved. I think the main point regarding Graylog Enterprise features is that it helps a lot in event analysis and identification because it brings in a lot of logs and a lot of information, so you can access all the information about the alert there. I believe Graylog Enterprise's AI features are very good, allowing you to use AI to run specific searches, which brings a lot of results. Regarding the AI features of Graylog Enterprise, I did not use them in such depth as to accurately evaluate their reliability, but I believe that AI can help speed up analysis and identify some suspicious patterns, though it is important that the result is always validated by an analyst.

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.
