Dennis O'Reilly - PeerSpot reviewer
Cyber SecOps Principal at Dotcom Security
Provides end-to-end antivirus protection and has good stability
Symantec Endpoint Protection provides end-to-end protection. Along with antivirus protection, it has a lot of key areas, including intrusive prevention, firewall features, and application and device control. It can integrate with other Broadcom solutions, such as Symantec Messaging Gateway and Symantec DLP. If you want to send an email, it gets scanned through endpoint protection and DLP. We get all Symantec functionality in a single pane.
Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.

Quotes from Members

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

Pros

"The stability is excellent."
"Overall, the product supports everything already feature-wise, because it has email protection, monitoring detection, network intrusion detection, and advanced threat protection."
"The Application Control code and the easy integration are valuable features."
"It has certainly helped out our audit efforts because we each stay compliant in terms of various security standards."
"They manage to solve detection quite nicely, with rather elaborate detection compared to other providers, and Symantec also provides a useful set of information linked to each of the attacked computers."
"The great advantage in using this product is it creates multiple services."
"Symantec Endpoint Protection provides end-to-end protection. Along with antivirus protection, it has a lot of key areas, including intrusive prevention, firewall features, and application and device control."
"The incident management on the solution is very good. You get a lot of detailed information about an incident. You also get a lot of documentation in connection with the CVI or integration."
"What I appreciate the most about The NodeZero Platform by Horizon3.ai is its distinctive competitive advantage, which is the ability to bundle multiple security solutions into one single tool."
"The automated updating of scans has been a huge value-add for us; we're a small cybersecurity team, so speed to value is the biggest thing to multiply the force of our small team, saving a lot of man-hours."
"The return on investment from The NodeZero Platform by Horizon3.ai is almost one hundred percent."
"We chose The NodeZero Platform by Horizon3.ai because, first, of its superior technical capability for the use cases we were looking for, second, the cost, which we believe was much more affordable than the other products, and third, the customer and technical support was very good for us."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization."
"Right now, using it for networks is great, and you could really do a lot with their continuous testing, which I thought was a great feature."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by catching vulnerabilities and exploits that we wouldn't otherwise be able to find as easily or as quickly, so I'd say it helps better our cybersecurity posture."
"Penetration testing and scans are useful features."
 

Cons

"The product's support services need improvement."
"Scalability could be better."
"An improvement could be made on the reporting because then it would be easier to collect information and submit it for compliance."
"They could enhance the solution to work across all devices, including Android, iOS, and Mac, and make it more user-friendly."
"There are limits with respect to blocking files by hash value or blocking IP addresses, and these limits should be removed."
"It should be able to collect information if the agent is disabled."
"I think SonicWall and McAfee are better solutions."
"The endpoint protection looks old."
"The NodeZero Platform by Horizon3.ai could greatly improve their feature request and product suggestions process."
"The setting up of new runners in The NodeZero Platform by Horizon3.ai could be simplified a little bit; currently, it's kind of a three-step process where you have to set up the assets in a separate menu, then a separate menu to set up a template, and then you actually set up the runner, so it would be nice if from the runner creation screen it just took you through the whole process instead of having to navigate to three different tabs."
"The NodeZero Platform by Horizon3.ai can be improved in some ways, particularly regarding the test scan sometimes."
"The areas for improvement for The NodeZero Platform involve integration and automation. It would be beneficial if it could integrate directly with vulnerability management tools that would allow the platform to automatically import data, identify vulnerable systems, and test targets immediately, potentially even enabling automated feedback loops for rescanning since the process is currently manual."
"Occasionally, I will get one that does not offer a lot in the way of specific steps because the device on which it found the vulnerability is not a standard device that it recognizes."
"When it comes to the stability of The NodeZero Platform by Horizon3.ai, I would rate it around seven to eight because the stability is not that high initially due to the need for daily updates and modifications as new vulnerabilities appear."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"However, my team struggles with the onboarding side of our engagement, which should have been more robust; having a statement of work and a clear definition of success would have been beneficial."

"Pricing is good. It is nice to have a great product at a fair price."
