Gained full visibility and streamlined threat detection through behavior-based insights and AI integration
Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.

Has delivered automated threat response and streamlined integration with advanced tools
The best features of Microsoft Defender for Business include it coming as an XDR solution which provides automated investigations, remediations, and endpoint detection and response. Moreover, it can be tightly integrated with vulnerability management or detecting vulnerabilities and pushing them to the SIEM solution. I utilize the advanced threat hunting feature of Microsoft Defender for Business and find it helpful; it's good and improving with every update. Microsoft Defender for Business integrates effectively with the Microsoft ecosystem as with Azure Sentinel, and it has a two-way natural integration. Apart from that, it also integrates with industry SIEM solutions such as Splunk.

Centralized policies have improved remote endpoint control and have simplified data visibility
The integration is not simple and easy. It requires experienced users or people who have done the implementation. When certain policies are applied, they do not immediately push the policies. For example, we manage endpoint device USB access. We set a policy to block it, but it does not come into effect immediately. Sometimes it takes three or four days for it to reflect. That is a pain point. I have raised this issue with support as well, but they said that I need to limit the number of devices in the policy. In terms of application deployment, for us, it was seamless.

Quotes from Members

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

Pros

"I have found the solution to be very easy in respect of the integration and configurable."
"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."
"The product's initial setup phase is very easy."
"The solution allows control over the user and his machine through Cortex XDR security policies."
"The initial setup is pretty easy."
"The scalability of Cortex XDR by Palo Alto Networks is very good."
"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."
"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."
"The security features in Microsoft Defender for Business that have been most effective for our company include the way it's built-in and intertwined into all the operating systems, giving us a good opportunity to holistically block things for the organization using that tenant."
"Defender is top class in terms of functional security."
"The most effective features of Microsoft Defender for Business include its threat detection and response capabilities in managing vulnerabilities and ransomware attacks."
"I would recommend Microsoft Defender for Business to others, rating it as ten out of ten."
"Microsoft Defender for Business is good for small and medium-sized businesses. It offers solid security flexibility and integration with tools like Microsoft Lighthouse and some other software. It takes some of the features of Defender for Endpoint EDR and provides those services for small and medium-sized business environments."
"I haven't had any problems with the tool's stability."
"Using Microsoft Defender for Business is beneficial for my company."
"The solution includes attack-savvy service and risk protection, part of data center management, and offers an effective single-dashboard view with Microsoft 365."
"Tanium's most valuable feature is its instant discovery aspect."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"Tanium is highly scalable."
"I would say Tanium is the best tool for vulnerability management."
"The interrogation piece was the most valuable feature because it was very detailed."
"I like the tool's incident response and security patching."
 

Cons

"Fine-tuning the detection policy requires experience because the policy is very complex in Cortex XDR by Palo Alto Networks, and we get high false positive alerts."
"Traps doesn't work with McAfee. You need to remove McAfee to install Traps. This is very common, and its nothing that should be an issue. Some antivirus engines recognize Traps as an threat component, so maybe they need to shake hands somewhere."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."
"We had a problem with getting our older endpoints up to date, but their newest updates have been really good. I've been pleased with it in terms of what our needs are. It's doing what we want it to do."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."
"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."
"Defender's threat protection should be fine-tuned to reduce false positives. It could be more targeted, reflecting a continuous evolution in detecting. Also, it could be easier to integrate into other environments."
"The security could always be improved."
"We faced some issues while running some applications on Mac."
"Defender's reporting is rather scattered, and its URL filtering mechanism doesn't really work."
"Technical support could be faster to respond."
"Microsoft should provide batch management solutions with the application, integrating pass management with roles."
"I have an open case for close to two months with no responses or updates, except for an email response, and I've made four or five phone calls regarding the Microsoft Interconnect for AD and cloud tenant."
"I am not satisfied with Microsoft's technical support. There are challenges with the knowledge and experience of the support staff, frequent redirection between departments, and slow response times."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"The solution needs to improve the reporting and tracking capabilities."
"They could improve the UI."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
 

Pricing and Cost Advice

"It is "expensive" and flexible."
"The pricing is okay, although direct support can be expensive."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"It has reasonable pricing for the use cases it provides to the company."
"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."
"The tool is cheap, while some other solutions are more expensive. I remember the tool cost about five euros for a workstation or for a user on a monthly basis."
"It has to get more competitive because we are starting to see some of the competitors providing better pricing, and some of it, of course, is to gain market share. The Defender product pricing is probably a little higher than the competitors."
"Defender for Business is included by default with an Office 365 premium subscription."
"Since we're a nonprofit, we get pretty good discounts on the tool."
"The tool's cost has been a little high, but I do not think it was terrible."
"The solution offers value for money."
"The solution is expensive but it's a good investment."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"It's an expensive solution. It would be nice if the cost were lower."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"There is an annual license required to use this solution."
"It is higher than some competitors in the market."
