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

"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."
"One thing that I like about Cortex XDR by Palo Alto Networks, it is detecting all the suspicious or malicious binaries, and it has integration with Palo Alto Firewall."
"The scalability of Cortex XDR by Palo Alto Networks is very good."
"Cortex XDR is stable, offering high quality and reliable performance."
"Cortex XDR by Palo Alto Networks is specifically designed to prevent zero-day attacks and is part of an ecosystem of Palo Alto, providing customers with a long-term vision to modify and redesign how security is applied in their company."
"Monitoring is most valuable."
"Previously, we had to install endpoint protection per machine and then scan and update, but Cortex XDR basically does that centrally and predictably, so we have more time to do day-to-day work rather than spend time chasing those endpoints."
"The initial setup is pretty easy."
"The most effective features of Microsoft Defender for Business include its threat detection and response capabilities in managing vulnerabilities and ransomware attacks."
"Microsoft Defender for Business offers the best pricing option in the market and is very cost-effective."
"Microsoft Defender for Business works well with the Microsoft Azure Security ecosystem, including Defender for Endpoint and Office 365 Cloud."
"Because Microsoft Defender for Business is a native solution to Microsoft 365, it has contributed to my organization's proactive defense strategies by saving time on integration."
"Defender's main strength is its integration with Microsoft Sentinel, offering valuable insights."
"I recommend Microsoft Defender for Business to startup organizations looking for a plug-and-play solution."
"The solution includes attack-savvy service and risk protection, part of data center management, and offers an effective single-dashboard view with Microsoft 365."
"The solution is effective, continuously improving, and highly regarded, especially with Microsoft's leadership in the industry."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"For inventory purposes, it's from one of the best things on the scene, as you can get live inventory."
"Tanium is used for endpoint management, specifically patching and configuration management."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"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."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"Tanium's most valuable feature is its instant discovery aspect."
"The interrogation piece was the most valuable feature because it was very detailed."
 

Cons

"Product might have some bugs."
"It'll help if customization was easier."
"There are some limitations on the Traps agents."
"Cortex XDR is trickier to configure than other Palo Alto products. This is one area where we are not so satisfied."
"I have faced some issues with Cortex XDR by Palo Alto Networks; there is room for improvement in the sense that certain options prevent us from seeing and segregating data."
"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."
"The price could be a little lower."
"The connection to the internet has not performed as expected."
"The pricing of Microsoft Defender for Business has a long way to go since people are still preferring solutions such as CrowdStrike and Palo Alto."
"The security could always be improved."
"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."
"I see room for improvement in Microsoft Defender for Business, particularly regarding the consolidation of all security solutions in one place and the integration of AI and data security into the same platform."
"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."
"The user interface has a lot of features which can make it complex and hard to adapt to for some users."
"Threat protection could be improved even though it is already a built-in feature."
"The solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"We had some issues with the solution's OS upgrade."
"Our biggest issue with the solution is its lack of mobility."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"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."
"In my opinion, sometimes it takes a long time to give solutions or resolve the issue."
"The solution needs to improve the reporting and tracking capabilities."
"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."
 

Pricing and Cost Advice

"Cortex XDR's pricing is ok."
"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."

"Defender for Business is included by default with an Office 365 premium subscription."
