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

"Endpoint to network is a good feature, it can protect the line."
"The great advantage in using this product is it creates multiple services."
"The most valuable feature is Click-time URL protection."
"They have a very simple and easy implementation; they have been around for a long time, and they have been very easy to deploy, support, and manage."
"Real-time threat analysis is quick and takes action on threats immediately."
"The technical support services are excellent."
"Technical support has been helpful and responsive."
"The product integrates well with our systems, and we have not encountered any problems."
"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."
"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 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."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"The NodeZero Platform's real attack capabilities help identify vulnerabilities on my on-premise systems by adding an element of validation and offensive security testing on top of known vulnerabilities. The feature that allows security teams to fix and retest vulnerabilities instantly is very useful, even though it may not happen literally 'instantly.' It's a necessary tool for any organization to understand whether vulnerabilities are genuinely exploitable by attackers. With its near-real-time testing capabilities, it's an essential part of any security portfolio."
"I rate the stability of the NodeZero Platform a ten out of ten."
"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."
 

Cons

"There are some ‎features that would add value to this product. One of them would be a graphical presentation of threats that the system has encountered."
"The product's support services need improvement."
"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."
"I think SonicWall and McAfee are better solutions."
"The endpoint protection looks old."
"Entire threat protection is not available for the advanced features."
"Scalability could be better."
"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."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"You need to be cautious about what it scans, as it could potentially cause issues."
"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."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"I haven't really come across anything that I say needs to be improved with it, other than the container runner, which tends to lose time."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"If we have had problems, that is with the actual licensing style they are using."
 

Pricing and Cost Advice

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