Featured Reviews

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.
Jörg Köhler - PeerSpot reviewer
Enhances remote access and integration with third-party tools
I use NinjaOne for managing smaller clients, specifically their devices and software, for small to medium businesses. I provide remote management services through NinjaOne. It allows clients to use NinjaOne for remote access to their computers for home office purposes. This feature is highly…

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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 saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"The most relevant feature is the monitoring, which provides built-in tools for sending commands."
"The solution's most valuable feature is related to its remote access...I know that NinjaOne's technical support is good."
"Good at managing updates and for remote support."
"NinjaOne is a great product. It is working and it is always developing."
"The installation is easy, it only took two minutes."
"NinjaOne's best feature is its monitoring."
"The tool's most valuable feature is third-party application updates."
"The best feature of NinjaOne is the SLA system. Every IT person can check their performance, how long it takes to resolve an issue, and how many SLAs are breached."
"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"The solution provides time saving and cost saving benefits."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"The support has been really cooperative."
 

Cons

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"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."
"The inclusion of XENServer and Proxmox as virtual platforms in NinjaOne is currently missing."
"NinjaOne's reporting module is cumbersome."
"Improvements could be made to reduce NinjaOne's functionalities to focus more on inventory or remote help tools."
"The ticketing system in NinjaOne is not the best."
"I want NinjaOne to improve the reports."
"The remote connectivity could be better. It works most of the time, but sometimes, there are issues."
"The NinjaOne distribution server is highly dependent on an active directory."
"The solution could improve by optimizing the internet connection being used."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"The product could have unique features similar to one of its competitors."
"The product must be more comprehensive."
"The professional version is not very scalable."
"In terms of what could be improved, I would say its reporting portion."
"The price could be reduced."
"Scans aren't done properly and some devices aren't pinged."
"Tenable Nessus is not feasible for a large company."
 

Pricing and Cost Advice

Information not available
"We got a pretty good deal. It was fairly affordable."
"I rate the solution’s pricing a five out of ten, where one is the lowest and ten is the most expensive."
"NinjaOne's price is fine since my workplace is an educational institution, so we get the product at a really good price considering that we do not pay taxes, making the prices very fair and worth the product."
"Its pricing is great."
"The product's pricing depends on the number of PCs or devices."
"We currently pay $1.20 per device on a monthly basis."
"It roughly costs $400 a month. It provides a good value because of the number of tools that you get in the solution. I would rate it a four out of five in terms of pricing. There are no additional costs other than the standard licensing fees."
"NinjaRMM uses a subscription model."
"There is an annual license required to use this solution."
"The price of Tenable Nessus is too expensive for each service center."
"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."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"Cost-wise, it's an affordable tool."
