Compliance and cost-effectiveness have improved while critical infrastructure security adapts to evolving needs

ArcSight Logger fulfills compliance requirements and passes audit requirements. It is one of the Aramco standards requirements and is recommended by Aramco for any implementation. Aramco, SABIC, water companies, and electricity companies are critical infrastructure with air-gapped networks. In an air-gapped network, there is no communication going out from that network area to the outside world, even to the corporate network. ArcSight Logger is installed on minimal resources with minimal requirements. There are not many upgrades or new features that come up frequently, though they do occur occasionally.

Robust event correlation enhances operations, yet integration scope can broaden for seamless data handling

The features and capabilities of Graylog that we have found most valuable are related to its basis on open search, which was ElasticSearch. We appreciate being able to integrate custom feeds and do custom parsers, and to be able to do some of the correlation on it. That all works effectively. 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. We use it for investigating problems and problem management. We throw all the information at it, we have it alerting for certain conditions, but generally we use it for deep diving into issues as needed.

Quotes from Members

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

Pros

"The ability to customize the solution in great detail is its most valuable features. We can customize the use cases and also have the ability to do scripting. We can personalize our dashboard as well. The scalability the solution offers is quite impressive."

"The most valuable feature is the search capability, which is simple to use."

"In terms of ArcSight Logger's most valuable feature, it is their scalability. ArcSight's real advantage is its scalability because they have two layers, including the logger layer."

"The most valuable feature is the level of detail that you can see about certain events, even when they do not come up in the console."

"The solution provides information about the risk factors."

"We haven't had any crashes or bugs. It is stable."

"In our country we are a little bit private in terms of solutions, so we are just starting to use the basic data capture. Now some users can start to use additional features that come with Micro Focus ArcSight like user behavior analytics for investigating."

"ArcSight's robustness is its most valuable feature."

More ArcSight Logger pros

"This had increased productivity for the dev and support teams, because we are directly notifying them."

"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."

"The product is scalable. The solution is stable."

"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."

"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."

"Message forwarding through the in-built module."

"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."

"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."

More Graylog Enterprise pros

Cons

"We find that the search and access functionality is quite slow."

"The initial setup was a little bit complex."

"They are migrating to Splunk because ArcSight Logger doesn't have those features for user or customer behavior analysis."

"The solution could be improved in maintenance settings."

"The speed of Logger indexing and searching for certain bugs for some queries that we provide could be improved. It can handle a huge number of logs but it can be improved."

"I think the ArcSight team should try to simplify legacy products for the customers, because that product is not easy to use or to work with. It needs more more competency or appeal to use. We hope Micro Focus is trying to resolve this."

"I would like to see better scheduling in the next release of this solution."

"You have limited reporting capabilities and I wouldn't choose ArcSight Logger for this purpose."

More ArcSight Logger cons

"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."

"I would like to see some kind of visualization included in Graylog."

"Dashboards, stream alerts and parsing could be improved."

"Its scalability gets complicated when we have to update or edit multiple nodes."

"The area in Graylog that needs to be improved or enhanced would be the integrations."

"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."

"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."

More Graylog Enterprise cons

Pricing and Cost Advice

"The pricing is quite harsh."

"Pricing is reasonable compared to similar tools on the market. They offer perpetual licenses."

"ArcSight is an expensive solution."

"It's not cheap at all as it's a big product and has been in the market for quite some time now."

"I would rate the product a seven out of ten since it's an enterprise product."

"ArcSight Logger is very expensive compared to their competitors, but when we talk to the customer and explain what the features are and how we can scale, they understand. Still, ArcSight is more expensive than the competition."

"We have a lifetime license, so we don't pay a monthly fee."

"I rate the product’s pricing a seven out of ten, where one is inexpensive, and ten is expensive."

"We are using the free version of the product. However, the paid version is expensive."

"I am using a community edition. I have not looked at the enterprise offering from Graylog."

"It's an open-source solution that can be used free of charge."

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog."

"You get a lot out-of-the-box with the non-enterprise version, so give it a try first."

"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."

"Having paid official support is wise for projects."

"We're using the Community edition."
