Alien Vault is a great product, which I have used over at my previous job and had purchased and installed at my current position too. Alien Vault is being primarily used by the IT team, but since it protects our entire network benefits the business in its entirety. Once the team has overcome the initial flood of notifications and had fine-tuned the alerts, the product is great and you know that each alert requires investigation, which in the long run will help us mitigate issues with cybersecurity.
  • Monitoring and alerts are great, once fine-tuned.
  • The interface is as user friendly as it can be, considering what AlienVault does.
  • It is based off open source products and as such can be deployed for free (it is a bit more limited than the paid-for product, but still does the trick for small business owners).
  • Can be overwhelming when you first set it up.
  • Some of the terminology can be tricky to understand.
  • Could allow for a bit more log storage on its lower tiers of subscription.
It is a great product for any size organization and scales very well as the company's demand increases. Because it is built on open source technology, its inner workings are more or less auditable by anyone that would like to so, it will be difficult to have back doors installed in the product. The alerts are great, you can also have them automatically perform actions, based on different scenarios.
It can be a bit pricey, but the support is great and well worth it for a medium to large enterprise.

We're currently on a migration path to eliminate AlienVault OSSIM but it was our only SIEM when I first arrived on location. We use it to collect and analyze security data from a variety of sources. Kind of like a receiver is used to merge audio sources from a bunch of disparate systems.
  • It integrates with a bunch of different platforms.
  • Collects tons of data from all integrated platforms provided the right level of logging is enabled.
  • The reports are clunky and a bit tedious to parse through.
  • Sometimes there's so much noise it's hard to tell what a true positive is. There are lots of false ones that trigger alerts but are normal behavior in many environments.
If you want a SIEM and you are a small-to mid-market organization getting security monitoring started, then this is a great SIEM for the money. It comes with a vulnerability scanner. While vulnerability scanners aren't all that expensive, this saves time and money by offering an industry-leading open-source version that enables managers to immediately start vulnerability management programs.
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.

AlienVault OSSIM is being used across the entire organization. We use the tools to assist in computer security, intrusion detection, and prevention. It provides effective threat detection, incident response, and compliance management, all done within a single appliance. The analysis is run in the background so we don't have to look at all the threats individually and research them from scratch.
  • Threat analysis. It can correlate different events happening to detect a pattern or an attack.
  • Dashboard provides a clean, single location to see what is going on in our environment.
  • Up to date open threat exchange means everything new popping up out there is included and watched for in our environment.
  • Reporting is not the greatest. I had internal developers take data and create some reports that better fit my needs.
  • Navigation through the vulnerability scans is not ideal.
  • Asset management is also cumbersome to navigate through.
AlienVault OSSIM is great for organizations that do not have a large staff and cannot afford to dedicate an entire person or group of people to deal with threats and monitoring the environment. The cost is also very reasonable for the amount of functionality of all the features we receive from the product.
AlienVault OSSIM support has been very good. I have not had an issue that they were not able to quickly identify and provide a fix for. They are very quick to respond to open cases and are very knowledgeable in the product, which makes troubleshooting issues fast and solutions are provided quickly.

Anyone who works in a K12 public school district knows you have just as many threats inside your network as outside. Think about it, what else do 7 through 12 graders have but time and curiosity? I've set this up on my perimeters at each of my high schools and middle schools, and again at the district level. My goal is to watch the traffic and devices inside each building and also across the buildings. We use it daily to monitor for unusual activity, devices, or strange "stuff" on our network.
  • Scan network for anomalies once you've established a baseline.
  • Excellent job of showing unusual connections or file transfers
  • Excellent job of showing the health of network, congestions, etc.
  • It only comes with 10 canned reports. These reports are good, but a little more flexibility would be nice. The data is stored in a database, so it is possible to roll your own reports, just very clunky.
  • Log ingestion. The OSSIM product doesn't have a separate log server, so you either have to have a really, really beefy system to do both analysis and log ingestion, or just do log ingestion with something else.
  • Aggregation of data. Actually, it does this really well, but if you have more then two sites, it can slow your analysis down a little.
AlienVault OSSIM is an excellent starter SIEM—you have a fully functioning SIEM in a few hours (installs in less than one, but takes a few to configure, based on your network). The insight you get, immediately is worth the time setting it up. If you are willing to invest some more time, you can fine tune it to really provide deep insight into your network. I really love that it is still free (was nervous when AT&T bought AlienVault).

Each of MyBuildings is routed back to the core - reduces overall traffic and adds one more layer to the network for security reasons. So having an "eye" in each building is necessary at this point. Not sure what I would do if I had to stop using them. The only other thing I plan on doing, in the process of rolling it out right now, is to add some netflow analysis.
Everytime I had a question, they were very willing to help. Not that I called often.

AlienVault OSSIM address's several business problems including but not limited to.
  • SIEM
  • Reporting
  • Asset management

OSSIM allows all this to be done form a single management platform saving time and money in having to use multiple platforms to complete daily tasks. With the OSSIM you will need a separate syslog server to allow the collection on logs
  • SIEM - Curtail part of managing your alarms and events on the network
  • Reporting - Ability to complete one click reporting for most compliance needs saving time and resources
  • GUI - The user interface is clean, and easy to use and customise
  • Data logging - Note this is available via their paid version USM
  • Plugins - More API plugins to aid the collection of logs form other security platforms
  • Threat Map - Did not appear to work
OSSIM is suited for security researchers and system admins who want quick visibility of network activity and alerts they may have missed without the aid of Alien Vault OSSIM. After a setup that only takes around 15 to 30 minutes, you will be seeing network traffic and generating alarms on your dashboard making it fast and effective deployment.

AlienVault OSSIM is our lightweight, open-souce option for SIEM and vulnerability assessment in our company and recommended for deployment in our clients. OSSIM, besides being open-sourced (hence, free of charge, although also free of support), is very flexible being mounted over a special Linux distro (Debian-based) and easily installable either on physical or virtual servers. Despite being a lighter version of the full-fledged AlienVault All-In-One solution, it's very much capable of handling daily maintenance and inspection IT tasks such as IDS (Intrusion Detection System), both network-based and hardware-based, SIEM correlation, Asset Discovery, and also includes the very useful AlienVault OTX (Open Threat Exchange) platform, allowing you and your organization to keep up to date in terms of threats and malicious devices worldwide that can affect your operations via open collaborative information.
  • 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.
  • OSSIM, being an open source solution, lacks log management (a treat that the full USM has). Perhaps a feature to include a lightweight version inside the SIEM Correlation engine can be appreciated.
  • The appliance also lacks support for Cloud-based servers and apps. This feature is also present in USM, so it's unlikely this will appear in OSSIM, but I'd suggest also a reduced version of it included in this appliance.
  • More integration with third-party solutions such as BMC Remedy and ServiceNow, although this can be emulated through email alerts, as most ITSM solutions have the ability of converting incoming email messages into tickets.
The most obvious scenario in which OSSIM is well suited is in a single office/home office (SOHO) or small business, in which budget is reduced but asset discovery and vulnerability management are greatly needed and appreciated. OSSIM is lightweight and free, so the real challenge to face is to hire or assign an administrator to manage and operate it, instead of any investment on an expensive appliance. Also, as resellers, promoting usage of OSSIM to customers charging for professional services for installation, administration, and maintenance (remember that OSSIM doesn't have official support from AlienVault) is a great asset for the organization.

AlienVault OSSIM is used in the organization as a log centralization tool and also as an event manager. We also use the feature of asset and availability management. The Netflow feature is also really helpful at diagnosing spikes of activity in the network, we also rely on it to detect suspicious activity.
  • Most of the configuration comes out-of-the-box suited for most environments. Setting it up is really easy, with the wizard, you can have it working in less than 3 hours of deployment, without counting asset installation.
  • Out-of-the-box dashboards are really useful. You can modify or add new widgets to suit your needs, but you'll most likely agree with what already comes configured.
  • The tickets feature for handling alarms is really easy to use.
  • The correlation directives that come out of the box are very few. I understand more correlation directives are a premium product, but one can hardly see the value of having very few. It makes new customers think they will not get better directives when they switch to the full USM or USM Anywhere.
  • Same with reports, the few reports it comes out of the box can be retrieved using other tools that are better prepared for the task. I understand that compliance reports aren't free, but at least I'd expect more security reports.
  • The OTX tab in dashboards sometimes takes too long to load, even if you have a fast internet and plenty of resources in the VM.
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.

It is currently being used by only the IT department. It is a fantastic tool to help with intrusion detection, asset discovery, SIEM correlation, behavior analytics, and a few other features. On the SIEM side, it does standard correlation, normalization, and collection. Being open source we use it only as part of a lab and not as our enterprise tool but it's been great working with it so far.
  • Being a part of the Open Source community, open source tools are always a big plus for me.
  • Being a simple straightforward tool, it does a great job especially with the asset management piece built into it.
  • Straightforward
  • Open Threat Exchange(OTX) gives a straightforward live threat intel feed to work off.
  • It's a free product! Yes, it doesn't have all the capabilities of the USM anywhere, but it does a great job. Can't really complain.
Small, medium or large, every company can benefit from this tool. Even if you decide to supplement your existing SIEM this is the way to go and chances are you might end up switching to this as your primary.
