Splunk Cloud Platform is a data platform service thats help users search, analyze, visualize and act on data. The service can go live in as little as two days, and with an IT backend managed by Splunk experts.
If this is your first experience with a SIEM, this one can get you started. Take the time to learn the ins and outs of the product and you'll most likely be satisfied with it if your company is an SMB. If you need compliance reports, OSSIM is too small for you, you'll need to go with USM or USM Anywhere.
Splunk is excellent when all your data is in one location. Its ability to correlate all that data is intuitive (once the hurdle of learning the query language is overcome). It is also easy to standardize the presentation of information to the company. When data is siloed/standalone, other systems can be cheaper and faster to implement.
Asset discovery. Once installed in a centric, network-accessible server, OSSIM can poll all your endpoints with common protocols (SSH, SNMP, WMI) to detect and discover site-wide assets to monitor. You only need to group them by your own criteria once added to the product.
SIEM Event Correlation. You can define quite complex correlation rules to detect possible suspicious or malicious actions or attempts in your network, in order to categorize them as real threats or as false positives, thus streamlining your risk assessment and management.
Ease of installation. The entire AlienVault OSSIM is self-contained in an ISO file, which can be burned into a DVD or just mounted in your server of choice (physical or virtual) for deployment. The installation process is automated and quote verbosed, with options for static IP, email messaging and others.
Ease of access. Being AlienVault OSSIM a self-contained appliance, it can be accessed via web by any device that supports a web browser, being that desktops, workstation, mobile devices, etc. The OSSIM dashboard and other features are automatically rearranged to adapt to the particular device being in use.
This SIEM consolidates multiple data points and offers several features and benefits, creating custom dashboards and managing alert workflows.
Splunk Cloud provides a simple way to have a central monitoring and security solution. Though it does not have a huge learning curve, you should spend some time learning the basics.
Splunk Cloud enables me to create and schedule statistical reports on network use for Management.
AlienVault OSSIM is far easy to use and manage - provided you know what you're doing. As any SIEM application, there is some background knowledge required in order to take advantage of the product's functionalities, such as the log correlation and analysis. Other than that, the application is quite usable and robust.
Everything is done through MSSP and installation pro services. Once those hours are burned up, then you're on your own without a lot of help. Typically the pro services hours aren't enough to get past 60 days and MSSP are hit and miss. We had a miss for installation helpers.
Splunk Cloud support is sorely lacking unfortunately. The portal where you submit tickets is not very good and is lacking polish. Tickets are left for days without any updates and when chased it is only sometimes you get a reply back. I get the feeling the support team are very understaffed and have far too much going on. From what I know, Splunk is aware of this and seem to be trying to remedy it.
Originally my organization leveraged alien value due to the lower cost of entry and ability to manage it as a service provider. Unfortunately, after several years of working with this tool, it became unwieldy to use as it felt that almost every useful report had to be created by hand. As other tools have come out with the ability to do automated responses such as Stellar Data processor, we have begun to evaluate alternatives.
Search Processing Language really is a game changer for writing easy-to-understand and maintainable queries on your data base logs. Once understood, setting up and validating a query can be done in no time- which leaves us the option to focus on more monitoring and improved services. We have no other tools that utilizes data this efficiently
