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.

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We receive infrastructure security warnings from it. So, we know what is going on and what needs to be addressed."
"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."
"Everything is in one dashboard; I'm notified when there's an incident and advised on what steps to take."
"The solution was consistently available, and I cannot recall any instances where it was down."
"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."
"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 has the ability to install agents. It is pretty straightforward. You can automate the process pretty easily."
"The quicker implementation of changes to our infrastructure from Alert Logic tell us if there are any problems."
"Tenable integrates well with other solutions such as SIEM and batch management."
"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"The most valuable feature of Tenable Nessus is the self-updating engine."
"User friendly and good dashboards."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
 

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."
"This product needs to mature more. While it is a good product, there are some areas where it needs work."
"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.""
"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 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."
"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."
"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."
"Its menu is not very intuitive. I would like to see the user menu expanded a bit. The user menu is very layered, and because of the layers, you have to go down a path that is not very intuitive."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"The price could be reduced."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"They should try to create an all-in-one solution."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"The solution could improve security updates."
"Tenable Nessus is not feasible for a large company."
"The price could be more reasonable. I used the free Nessus version in my lab with which you can only scan 16 IP addresses. If I wanted to put it in the lab in my network at work, and I'm doing a test project that has over 30 nodes in it, I can't use the free version of Nessus to scan it because there are only 16 IP addresses. I can't get an accurate scan. The biggest thing with all the cybersecurity tools out there nowadays, especially in 2020, is that there's a rush to get a lot of skilled cybersecurity analysts out there. Some of these companies need to realize that a lot of us are working from home and doing proof of concepts, and some of them don't even offer trials, or you get a trial and it is only 16 IP addresses. I can't really do anything with it past 16. I'm either guessing or I'm doing double work to do my scans. Let's say there was a license for 50 users or 50 IP addresses. I would spend about 200 bucks for that license to accomplish my job. This is the biggest complaint I have as of right now with all cybersecurity tools, including Rapid7, out there, especially if I'm in a company that is trying to build its cybersecurity program. How am I going to tell my boss, who has no real budget of what he needs to build his cybersecurity program, to go spend over $100,000 for a tool he has never seen, whereas, it would pack the punch if I could say, "Let me spend 200 bucks for a 50 user IP address license of this product, do a proof of concept to scan 50 nodes, and provide the reason for why we need it." I've been a director, and now I'm an ISO. When I was a director, I had a budget for an IT department, so I know how budgets work. As an ISO, the only thing that's missing from my C-level is I don't have to deal with employees and budgets, but I have everything else. It's hard for me to build the program and say, "Hey, I need these tools." If I can't get a trial, I would scratch that off the list and find something else. I'm trying to set up Tenable.io to do external PCI scans. The documentation says to put in your IP addresses or your external IP addresses. However, if the IP address is not routable, then it says that you have to use an internal agent to scan. This means that you set up a Nessus agent internally and scan, which makes sense. However, it doesn't work because when you use the plugin and tell it that it is a PCI external, it says, "You cannot use an internal agent to scan external." The documentation needs to be a little bit more clear about that. It needs to say if you're using the PCI external plugin, all IP addresses must be external and routable. It should tell the person who's setting it up, "Wait a minute. If you have an MPLS network and you're in a multi-tenant environment and the people who hold the network schema only provide you with the IP addresses just for your tenant, then you are not going to know what the actual true IP address that Tenable needs to do a PCI scan." I've been working on Tenable.io to set up PCI scans for the last ten days. I have been going back and forth to the network thinking I need this or that only to find out that I'm teaching their team, "Hey, you know what, guys? I need you to look past your MPLS network. I need you to go to the edge's edge. Here's who you need to ask to give me the whitelist to allow here." I had the blurb that says the plugin for external PCI must be reachable, and you cannot use an internal agent. I could have cut a few days because I thought I had it, but then when I ran it, it said that you can't run it this way. I wasted a few hours in a day. In terms of new features, it doesn't require new features. It is a tool that has been out there for years. It is used in the cybersecurity community. It has got the CV database in it, and there are other plugins that you could pass through. It has got APIs you can attach to it. They can just improve the database and continue adding to the database and the plugins to make sure those don't have false positives. If you're a restaurant and you focus on fried chicken, you have no business doing hamburgers."
 

Pricing and Cost Advice

Information not available
"Alert Logic has better competitive pricing than some of its competitors."
"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."
"Almost any product that is on the AWS Marketplace is super easy to subscribe to."
"Price of the solution was very reasonable considering the size of our organization at the time, and so it worked out perfectly."
"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."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"The price of Tenable Nessus could improve, it is expensive."
"The pricing is much more manageable versus other products."
"The is a free version of Tenable Nessus available."
"The solution has a single price for unlimited assets."
"The price of the solution is reasonable."
"There is an annual license required to use this solution."
"The solution is expensive."
