Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.

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.
HarshBhardiya - PeerSpot reviewer
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"It has the ability to install agents. It is pretty straightforward. You can automate the process pretty easily."
"Notifications and the detail of notifications are most valuable. It is a user-friendly solution."
"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."
"The installation and configuration were slick."
"It is a very stable product."
"While I still have on-premises appliances, I can remotely monitor everything from the cloud, and Alert Logic's ease-of-access features have helped me streamline my workflow and reduce implementation time."
"The solution was consistently available, and I cannot recall any instances where it was down."
"The quicker implementation of changes to our infrastructure from Alert Logic tell us if there are any problems."
"The solution is very stable."
"The solution is great for scanning servers."
"The solution can scale well."
"The scanning capabilities are most valuable when compared to Nessus."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"The plug-in text information is quite useful."
"The most valuable feature of Tenable Nessus is website scanning."
 

Cons

"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"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.""
"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."
"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."
"The documentation, especially with the initial setup, needs improvement."
"Could be more of an endpoint protector."
"The product needs to mature. We don't want to be bombarded with unnecessary issues and have the real ones slip through."
"We'd like to have triggered alerts sent to us so we see errors quicker."
"The setup process was complex."
"The price could be reduced."
"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."
"One area that has room for improvement is the reporting. I'm preparing reports for Windows and Linux machines, etc. Currently, I'm collecting three or four reports and turning them into one report. I don't know if it is possible to combine all of them in one report, but that would be helpful."
"Lacks some penetration testing-related services."
"The tool needs to upgrade asset tracking."
"It would be nice for the professional module to include some of the reports available in the expert module."
"Vulnerability recommendations are outdated and not in line with industry standards."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
 

Pricing and Cost Advice

Information not available
"Alert Logic has better competitive pricing than some of its competitors."
"Price of the solution was very reasonable considering the size of our organization at the time, and so it worked out perfectly."
"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."
"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."
"Cost-wise, it's an affordable tool."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"It has a fair cost and very good cost-benefit ratio."
"The solution has a single price for unlimited assets."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"We pay approximately $2,500 on a yearly basis."
"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."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
