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.
Jack Leung - PeerSpot reviewer
Easy to use and deploy agents but needs more stability
We just need to deploy the agent to the endpoints. We don't need to set up anything. For a single agent, it takes one or two minutes. However, we deployed globally, and you need to take into consideration the time it will take to deploy across each endpoint. It's very simple to deploy. We had three or four engineers take care of the implementation.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Its flexibility is most valuable."
"The fact that it's just one product that can patch multiple operating systems is really great."
"The flexibility in creating tools to make changes on remote machines is most valuable to me. The reporting feature is also fantastic because on any given day I can bring up a list of machines that don't have patches, for example. Or I can bring up a list of machines that are in my environment on a certain day. The solution helps me with not only my own role, and what I look for internally myself, but it also helps during audits. I can go in and look at the number of machines in there, and their owners and timelines. It certainly helps tell a story for anything that IT requires."
"Previously, we would run a report, scan it, and compare it. We were spending 15 to 30 minutes a month on each machine on this stuff because you would find stuff that wasn't up to date, then you had to fix it. This solution takes that time down to minutes. Automox saves us easily many hours a month."
"It's super easy to use and we haven't found anything easier."
"The biggest improvement to our organization involves the reduction in its man hours... We've probably saved hundreds of hours."
"Among the most valuable features are its ease of use and the Worklets. Both of them are time-savers. Worklets enable us to customize things for a given environment. It's something like when Apple lets other people create applications. Other peoples' Worklets can be used in our environment and in our customers' environments. That saves a lot of time, and it's really cool."
"They've been adding some new features lately, which I'm not nearly as familiar with, but the ability to just deploy patches and exempt certain machines from certain patches is helpful. For instance, for our servers, we may not want to roll out zero-day patches. We are able to exempt those and make sure that they don't get those policies. We've got certain servers that have to run a particular version of Java, and being able to exempt those servers from receiving Java updates is pretty fantastic."
"The vulnerability scanner is the most valuable feature."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The automatic scanner and scheduler are pretty cool."
"It gives you an unlimited IP scan."
"The initial setup is very straightforward."
"The trial version is very good for testing whether it will suit your needs."
"Scanners and reports using CIS templates ("de-facto" standard, easy to fix and to locate correction tips at documentation), tests against cloud providers, database profiles, several types of telecom devices, and others highly customizable scans."
"I like the fact that it was not expensive. I like that it's user-friendly."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"They need to improve the automation features."
"There should be better inventory capabilities. Right now, they only allow you to have insight into software out-of-the-box. It would be nice to also extend that into custom inventory that can be modified and managed by the practitioner."
"When we bring on a new client, we need to go into that client and manually set up my account, my chief engineer's account, three technicians' accounts, and a billing person's account all over again, which is annoying. We have probably up to 15 or 16 of our clients on Automox now. For every single one of those, we have had to go in and set this up. Then, if anything changes, we have to remember to go to Automox and change it 15 or 16 times. So, we just want inheritable permissions, and that is it. We have talked to them about this, and they are like, "Yeah, we hear a lot of complaints about it." I am thinking, "Guys, I have been complaining about this for a year and a half. When are you going to do it?" It must be some tricky thing or not an easy fix, because I can only assume if it were easy, then they would have done it by now."
"Asset management would be a great feature to add to Automox. We would run easier scripts or more out of the box scripts that would help us in audits. \"
"We would like to see additional detailed reporting for Service providers like us. We had to build our own reports via their APIs to meet our needs."
"It should have integrated workstation access. So, there should be a remote desktop feature."
"The stability has come a long way from what it was like when it started and now it's really good."
"As concerns the patching concepts, there's a bit of a learning curve in terms of working out how Automox wants you to work within the console, not only splitting up everything into groups, but then having the various policies assigned."
"I think the reporting templates could be improved with Tenable Nessus."
"We'd like to see the solution embrace more user-friendliness."
"Model OS costs (and its segregation schema for individual modules)."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"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."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"Lacks some penetration testing-related services."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
 

Pricing and Cost Advice

Information not available
"The product is a great value."
"For all these software tools, it is usually a subscription model. There is a monthly charge that we need to pass along to our clients because we are doing all this for their benefit. It is only a couple of bucks a month per computer, and that is a low enough price point where our clients, without exception, have accepted it, and said, "This is great. We will pay that. It sounds like a worthwhile thing.""
"The cost is very reasonable compared to the competition."
"There are no additional costs in addition to the extended licensing fees with Automox. You get your support and your per endpoint license with what you purchased."
"Automox just charges us a set amount per user, per month, for using the product. That is very important to us. Because it's a cloud-native solution, you're saving on the cost of hosting an on-premises solution on your servers."
"The pricing and licensing costs have been great for us... My advice to others who are evaluating or thinking of implementing Automox is to give it a shot. If a free trial is still available, definitely use it, because it makes life a lot easier."
"We are on the premium licensing, which is the one that has the API capability that we use."
"We're doing it annually directly through Automox. It is per endpoint. It is $2 and some change per endpoint, but I believe the cost is right around $28,000. Everything is covered in this fee."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"The price of the solution is reasonable."
"The solution is worth the cost. It's a good investment."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"I would like to see better discounts."
"In general, it is extremely expensive."
"The product is free."
"The price is reasonable."
