Fraud controls have protected patient portals and now support trusted digital healthcare access
Arkose can be improved in several ways. Integration complexity requires alignment with healthcare IT systems, which is an area where Arkose is currently lagging. There is a need to balance security versus patient experience, as overly strict controls frustrate legitimate users who want to access the patient portal without excessive restrictions. Evolving threats present another challenge. Every day, fraudsters use generative AI to mimic human behavior, which requires Arkose to continually improve its threat detection. Since Arkose handles different systems that need to be controlled over time, there should be regular audits to determine which features need adjustment. Cost-wise, the platform requires improvement, as there is significant cost involved and considerable manual intervention needed, which should be brought into the AI automation. On an everyday basis, patient login verification sometimes experiences delays when internet issues occur, causing patients to wait long in queue. Insurance claims validation does not always happen easily due to application environment downtime. These operational improvements need to be addressed in Arkose Labs systems.

Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Quotes from Members

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

Pros

"I also like that they challenge crawling in CAPTCHA for mobile. This is good compared to the traditional way."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"Microsoft Defender for Office 365 has decreased my time to detection and time to respond by one hundred percent."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"With Defender for Office 365, we have been able to increase the security posture across our organization."
 

Cons

"Integration complexity requires alignment with healthcare IT systems, which is an area where Arkose is currently lagging."
"Arkose need to provide something for testing."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"If you look at other products, such as Wiz or Palo Alto's cloud, because they also have similar components in terms of how they protect cloud infrastructure or enable cloud security, Microsoft Defender for Office 365 is not up to that extent."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"I assess the stability and reliability of the solution as seven out of ten."
