Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security ( /products/elastic-security-reviews ) is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.
Andrey Mostovykh - PeerSpot reviewer
Real-time analysis, easy setup, and open source
We stopped using it for analytics because of its price, and at the moment, we are using it mostly for log centralization. If you use it with high traffic for analytical purposes, as well as for the logs, the infrastructure costs are unbelievable. Graylog is a great product backed by Elasticsearch as the storage and query engine. It is just an interface on top of Elasticsearch and some Elasticsearch management. The indexes that are kept in Elasticsearch are managed by Graylog software. Elasticsearch is a decent product, but it's very infrastructure-heavy. It requires lots of resources, and if you make a mistake with provisioning, you are likely to not get a cluster back. We had a couple of outages like that, and we hated that. So, we ended up over-provisioning resources just to avoid such situations from happening. If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much. That may be my Norwegian take on it, but the engineering resources are expensive. It's better to just provision the infrastructure. Overall, the product is great, and the features are just fine, but the infrastructure cost is what is killing it. The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic. I'm not sure if they can improve the infrastructure cost with the way Elasticsearch is. If they keep using Elasticsearch, maybe there are some opportunities there, or they can support other backends with cheaper storage. They could have a different backend to replace Elasticsearch or do some tweaks to Elasticsearch to reduce the costs. There could be partial parsing of logs or parsing on demand so that when you write data through Graylog to Elasticsearch, it doesn't need to crunch in every detail requiring that much CPU.

Quotes from Members

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

Pros

"The stability of the solution is good."
"The most valuable feature is the machine learning capability."
"Elastic has a lot of beats, such as Winlogbeat and Filebeat. Beats are the agents that have to be installed on the terminals to send the data. When we install beats or Elastic agents on every terminal, they don't overload the terminals. In other SIEM solutions such as Splunk or QRadar, when beats or agents are installed on endpoints, they are very heavy for the terminals. They consume a lot of power of the terminals, whereas Elastic agents hardly consume any power and don't overload the terminals."
"It is an extremely stable solution. Stability-wise, I rate the solution a ten out of ten."
"The feature that we have found the most valuable is scalability."
"ELK is open-source, and it will give you the framework you need to build everything from scratch."
"It is very quick to react. I can set it to check anomalies or suspicious behavior every 30 seconds. It is very fast."
"The scalability is good. It can be scaled easily in the production environment."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"Graylog is very handy."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"The solution's most valuable feature is its new interface."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
 

Cons

"Authentication is not a default in Kibana. We need to have another tool to have authentication and authorization. These two should be part of Kibana."
"Elastic Security has a steep learning curve, so it takes some time to tune it and set it up for your environment. There are some costs associated with logging things that don't have value. So you need to be cautious to only log things that make sense and keep them around for as long as you need. You shouldn't hold onto things just because you think you might need them."
"The price of this product could be improved, especially the additional costs. I would also like to see better-quality graphics."
"The setup process is complex. You need a solid working knowledge of networking, operating systems, and a little programming."
"There is an area of improvement in the Logs list. The load list may need to be paginated as there are limits."
"I want to find an automatic security system in the tool, like a SOAR solution. I am looking forward to seeing a SOAR system in the tool."
"It is difficult to anticipate and understand the space utilization, so more clarity there would be great."
"Elastic Security consumes a lot of resources, requiring a substantial deployment setup."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
 

Pricing and Cost Advice

"Compared to other products such as Dynatrace, this is one of the cheaper options."
"This is an open-source product, so there are no costs."
"Affordable but with additional costs"
"Compared to other tools, Elastic Security is a cheaper solution."
"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"The solution is free."
"It is easy to deploy, easy to use, and you get everything you need to become operational with it, and have nothing further to pay unless you want the OLED plugin."
"The product offers an amazing pricing structure. Price-wise, the product is very competitive."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"It's an open-source solution that can be used free of charge."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"We're using the Community edition."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
