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.

Endpoint monitoring has strengthened incident response and provides rapid isolation and forensics
Tanium provides an endpoint which is isolated from the network and environment. We can easily search its logs and history and connect remotely directly to that particular device which has been isolated from the network. We can search for the history and logs, including audit logs and event logs. The complete activity of the user or owner of the device is visible to us. We can see the artifacts of particular USB transfers internally for official use. We can not only connect remotely but also see the device status and how many failures have occurred within the network so far. We can see the IP address, how many times it has changed its IP address, and how many times it was connected to VPN or external VPN or internal VPN and what has been searched while on VPN. We can block the IOCs or IP addresses as well. We can block domains, hashes, SHA values, SHA-256, SHA-1, SHA-5 and MD5. Although I am not completely involved in the automation team, we do have that team and I have worked in some CERT recently. Tanium is more useful while we are in the CERT because most of the times when we are on high alert, Tanium does play a main role for that particular incident or any high case. Tanium is a simple tool and we can easily integrate it to many devices and it is a mandatory tool to secure an endpoint. It is mandatory to give any RDP connection and the tool should be present in the particular device. It is completely mandatory and it is in the policy as well.

Quotes from Members

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

Pros

"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."
"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."
"In one single alert, we are getting the network telemetry, endpoint telemetry, email security telemetry, and proxy telemetry all in one single ticket, making it very easy."
"The product's most valuable features are massive user and feature intelligence exploit detection."
"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."
"The behavior-based detection feature is valuable."
"This software helps us understand any issues that may arise when someone is not at work."
"It detected stuff that other things wouldn't detect."
"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."
"The most valuable feature of the solution is its central console."
"I recommend Microsoft Defender for Business to startup organizations looking for a plug-and-play solution."
"Microsoft Defender for Business offers the best pricing option in the market and is very cost-effective."
"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."
"The solution is effective, continuously improving, and highly regarded, especially with Microsoft's leadership in the industry."
"Using Microsoft Defender for Business is beneficial for my company."
"I rate Microsoft Defender for Business a 10 out of 10."
"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."
"It's definitely not complex, it is pretty user-friendly and it's a solid tool enterprise to use."
"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."
"The solution's technical support is very responsive."
"The insights we gain from our endpoints and the management capabilities that Tanium provides have been a boon to our operations and security."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"For inventory purposes, it's from one of the best things on the scene, as you can get live inventory."
 

Cons

"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"I have seen lagging with Cortex XDR by Palo Alto Networks. There was one time when we faced a threat actor trying to gain access to our system. When our team utilized the tool, we were all on the same dashboard and we faced a lag issue at that time of around five minutes, which was quite significant."
"Dashboards do not allow everyone to see what's happening."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."
"Limited remote connection."
"The connection to the internet has not performed as expected."
"Talking with the tool's technician about any problem is very complicated."
"Technical support could be faster to respond."
"The solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."
"Additionally, the pricing policy poses a challenge, particularly in multi-year contracts, where other solutions like Trend Micro offer more affordable options."
"The biggest one is that Defender needs to be more proactive to the emerging threats. There can be tighter integration with email, especially how it integrates with our email system, which is the Microsoft Outlook suite. There should be the ability to react a lot quicker to emerging threats because sometimes, it takes a few days before some of these new threats are fully identified, and we need that to be a few hours."
"We faced some issues while running some applications on Mac."
"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."
"The tool's support is an area of concern where improvements are needed."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task."
"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."
"The problem or challenge is a pre-sales and go-to strategy for the SMB market delivered through a channel or model. It's very convoluted and vague, which leads to some confusion about the various types of modules, and the device-to-seat cost is extremely difficult to calculate."
"The most painful thing is the interface. It's a bit unclear sometimes."
"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."
"We had some issues with the solution's OS upgrade."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"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."
 

Pricing and Cost Advice

"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."
"Very costly product."
"The price is on the higher side, but it's okay."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"The price was fine."
"Our customers have expressed that the price is high."
"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."
"Since we're a nonprofit, we get pretty good discounts on the tool."
"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."
"The tool's cost has been a little high, but I do not think it was terrible."
"Defender for Business is included by default with an Office 365 premium subscription."
"It is higher than some competitors in the market."
"It's an expensive solution. It would be nice if the cost were lower."
"There is an annual license required to use this solution."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"The solution offers value for money."
"The solution is expensive but it's a good investment."
