It's a highly mature, competitively priced solution that provides total visibility into your ecosystem. FORTRA's Alert Logic has the only Cybersecurity Platform that integrates XDR+WAF+VM+DLP in one.
Alert Logic offers total visibility into the client's IT ecosystem. The solution's intrusion detection system inspects 100 percent of the network packets and installs universal agents on all physical and virtual servers for log collection. Alert Logic also aggregates logs of the client's various 3rd Party security tools into a single pane of glass. All of the analytics from those data feeds got to a 24/7 SOC with sophisticated resources. Alert Logic has massive threat intelligence resources to provide additional context to the incident response declarations. They do all the heavy lifting for clients who lack the technology and resources to operate their own SOC. The client is solely responsible for the incident response component. The macro analytics resides on Alert Logic's cloud. You have the ECM response and business application team on the client side. Everything works in tandem, which is the only way you can deal with the advanced threats we face today, especially the ransomware families. If you don't respond in minutes, you're in trouble.

Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"The initial setup is pretty straightforward."
"The installation and configuration were slick."
"We receive infrastructure security warnings from it. So, we know what is going on and what needs to be addressed."
"It improves our security. Before, we didn't have anything scanning our containers. We had software scanning all the physical servers, but we had nothing to scan our containers. With Alert Logic, we can do that."
"It is a very stable product."
"The quicker implementation of changes to our infrastructure from Alert Logic tell us if there are any problems."
"The most valuable aspect of Alert Logic is its technology platform. They have SOCs in the US and Europe, giving them global visibility of the threat landscape. They detect and respond to threats in minutes. Their biggest value is human expertise. You're being attacked by a human, and you cannot respond to it unless you have a human on the other side. They have the human and technological resources to respond."
"Notifications and the detail of notifications are most valuable. It is a user-friendly solution."
"The reports are pretty nice and easy to understand."
"The automatic scanner and scheduler are pretty cool."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
"It gives you an unlimited IP scan."
"The initial setup is very straightforward."
"A valuable feature of the solution is that it is easy to understand."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
 

Cons

"Alert Logic needs to expand its SOCs to serve more markets, such as the Middle East and Asia. There should be infrastructure that covers more time zones. The company should also develop an EDR that is natively integrated into their solution. Currently, a client must buy another EDR solution like CrowdStrike or Sophos. I think Alert Logic is developing this. Built-in email security could also be developed and integrated."
"I would like more data on the alert payload. It would be good to have the ability to customize the alert payload to add whatever data that we want on there. Right now, it is a bit limited."
"I would like to see it do initial scans and start capturing data, which it will truly analyze, not just be a reporting system saying, "Here is an email. Here is an email. Here is an email.""
"The product needs to mature. We don't want to be bombarded with unnecessary issues and have the real ones slip through."
"Could be more of an endpoint protector."
"We'd like to have triggered alerts sent to us so we see errors quicker."
"This product needs to mature more. While it is a good product, there are some areas where it needs work."
"They have ideas and email you whatever they find, but they don't have a dedicated security team who will work on an attack or a specific security instance."
"Tenable Nessus could improve the price."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"Scans aren't done properly and some devices aren't pinged."
"It would be nice for the professional module to include some of the reports available in the expert module."
"I think the reporting templates could be improved with Tenable Nessus."
"The product must be more comprehensive."
 

Pricing and Cost Advice

"Almost any product that is on the AWS Marketplace is super easy to subscribe to."
"Our ROI would probably be zero. We don't even use it. It sits in there. We get emails and just delete them. Around the world, we don't even use it."
"Alert Logic has better competitive pricing than some of its competitors."
"Its pricing is very reasonable considering what you get for what you pay. There is quite a good value there. Its licensing is also very logical. They've got the licensing price points at a reasonable level. It is on a monthly license but a yearly contract. There are no additional costs to the standard licensing fees."
"Price of the solution was very reasonable considering the size of our organization at the time, and so it worked out perfectly."
"The price of the solution is reasonable."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"The price of the solution is reasonable."
"The solution is expensive."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"I think the price is fairly affordable. It provides a license that is fair."
"In general, it is extremely expensive."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
