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."
"The product integrates well with our systems, and we have not encountered any problems."
"Endpoint to network is a good feature, it can protect the line."
"The most valuable feature is Click-time URL protection."
"Technical support is very responsive. You just have to open a ticket. They respond in a timely manner. Their response is good. I'm satisfied."
"Technical support has been helpful and responsive."
"The most valuable feature is NetFlow threat protection."
"The great advantage in using this product is it creates multiple services."
"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's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"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 my organization by allowing my security team to be more efficient and focus on the most valuable work at the highest criticality."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"Penetration testing and scans are useful features."
"The NodeZero Platform by Horizon3.ai is better than manual penetration test scans, definitely worth trying if you are considering using it because it reduces the time and cost associated with manual scans and presents the data in a very clear way that even non-technical people can understand."
 

Cons

"They could enhance the solution to work across all devices, including Android, iOS, and Mac, and make it more user-friendly."
"An improvement could be made on the reporting because then it would be easier to collect information and submit it for compliance."
"The administration interface needs a lot of improvement. It should be UI based, and simple. They need to improve it. It's pretty much not that friendly compared to what we were using as Bitdefender before. It's okay but is improving, actually."
"Scalability could be better."
"The endpoint protection looks old."
"The cloud platform needs to have improvement in terms of the user interface and the different capabilities it has available. It needs to match the other leading next-gen EDR products that are available in the market. That's the reason why we are stepping away from Symantec. Their cloud environment is just generally lacking in comparison to others."
"The product's support services need improvement."
"It should be able to collect information if the agent is disabled."
"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."
"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"The reports are quite useless."
"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 could be improved by speeding up the time from initializing a test to actually starting the test, as the deployment of the underlying infrastructure can take several minutes, sometimes over 10 minutes."
"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."
 

Pricing and Cost Advice

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