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

"You don't have to buy a separate email security platform. You can enable that using their endpoint, and I like that. You don't have to have two agents running on the same box."
"The most valuable feature is NetFlow threat protection."
"It has certainly helped out our audit efforts because we each stay compliant in terms of various security standards."
"The Application Control code and the easy integration are valuable features."
"The most valuable feature is Click-time URL protection."
"The great advantage in using this product is it creates multiple services."
"Their integrations are pretty good as are their Sandbox solutions, their proxies, and their LTAs with API or ICAP protocols."
"Technical support has been helpful and responsive."
"I believe that The NodeZero Platform by Horizon3.ai has kept me safer in a cybersecurity sense."
"The NodeZero Platform by Horizon3.ai has positively impacted our organization by definitely increasing our security posture significantly."
"If someone was looking into this product, I would absolutely recommend it."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by improving our cybersecurity score; we have reduced many of our vulnerabilities and we are hoping that our cyber insurance will decrease due to the hardening that we have done."
"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."
"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."
"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."
 

Cons

"Solutions like CrowdStrike, ESET, and SentinelOne have really jumped ahead on behavioral and algorithm-based detection capabilities. Symantec is trying to catch up, but they still have some limitations of being an old-school AV protection program and adding AI and behavioral learning and detection algorithm."
"Entire threat protection is not available for the advanced features."
"The support for new OSs and older OSs could be a little tighter. They need to be more upfront about what protection services they're going to provide on new OSs. I haven't seen the Windows 11 version out yet. It is either already released in Beta, or the Beta will be released soon. There could be a little bit more advanced updates on what they're doing to help protect Windows 11 environments. They can let us know in advance so that we know it is going to be protected. We can't roll out the new OS without putting end-point protection on it. So, they should tell us what is their support model for that, and what are they doing to protect Windows 11. They're not telling me, and that's a criticism. The same issue is applicable to all the other antivirus tools. It is not just Symantec; all of them have this problem."
"The support has dropped down to a five out of ten."
"It should be able to collect information if the agent is disabled."
"The endpoint protection looks old."
"Not ideal for advanced threat protection."
"Symantec appliances need improvement. The whole appliance environment is a robust system and it needs a massive amount of storage space. If you have to increase or speed up the background storage it's a pretty complicated process. The scalability and sizing is critical, and if you do it wrong you run into issues pretty quickly."
"The NodeZero Platform by Horizon3.ai could greatly improve their feature request and product suggestions process."
"You need to be cautious about what it scans, as it could potentially cause issues."
"Sometimes even their support doesn't know why we're seeing certain issues."
"I feel there could be improvements in scalability, although at this point I have no specific negative points to report."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"I would like to see an improvement in the notification management."
"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."
"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 and Cost Advice

"The pricing of this solution is inexpensive and affordable."
"The price is quite expensive."
"Symantec Endpoint Protection has an average price."
"Pricing is good. It is nice to have a great product at a fair price."
"Symantec Advanced Threat Protection's pricing is comparable."
