Executive SummaryUpdated on Feb 8, 2026

Avanan and Microsoft Defender for Office 365 are both leading contenders in the email security solutions category. Avanan appears to have the upper hand due to its customizable features and ease of use, especially for smaller teams, while Microsoft Defender offers comprehensive integration and threat protection within Microsoft ecosystems.

Features: Avanan provides advanced anti-malware capabilities, efficient end-to-end email encryption, and customizable rule support which enhances real-time threat alerts. It also offers a user-friendly interface for non-technical users, making it ideal for smaller organizations. In contrast, Microsoft Defender integrates seamlessly with Office 365, offering robust anti-phishing mechanisms and broad protection across the Microsoft suite. Its integration with Microsoft Sentinel provides enhanced threat visibility and response within diverse platforms.

Room for Improvement: Avanan could enhance integration with leading SaaS applications and refine its AI-driven threat detection to minimize false positives. Improving compatibility with non-email threat vectors and providing more comprehensive tutorial support would be beneficial. Microsoft Defender could improve its support for non-Microsoft file types and offer enhanced threat intelligence alerts and detailed reporting. Streamlining its dashboard and providing clearer documentation would help ease navigation and setup.

Ease of Deployment and Customer Service: Avanan offers streamlined deployment across private, public, and on-premises clouds with rapid adaptability to varying user numbers, coupled with excellent customer service treating clients as partners. Microsoft Defender, while mostly operated in public and hybrid clouds, requires more intricate setup. Its support teams are knowledgeable but need streamlined processes for better user experience. Simplifying the onboarding process would make deployment faster and more accessible.

Pricing and ROI: Avanan offers flexible pricing arrangements aligned with usage patterns, providing significant cost-effectiveness and rapid ROI by reducing phishing incidents. Microsoft Defender, part of broader Microsoft suites, integrates within Office 365 subscriptions. Although perceived as costly due to bundled capabilities, its comprehensive integration often justifies the expense through enhanced productivity, offering substantial value particularly for larger enterprises with consistent software ecosystems.

Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

Enhances email security and has a very simple and easy-to-use UI

Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

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

"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."

"It will take the blow rather than our applications should an attack occur."

"The blocking feature is very good."

"Cloudflare is simple to use."

"Cloudflare Access is part of the Zero Trust philosophy."

"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."

"Cloudflare, in my opinion, was easy to implement."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

More Cloudflare One pros

"If we look at four to five years ago, we had close to six or eight people click a link in an email per month. Now, we are probably down to about five or six clicks a year, if not less."

"I like Avanan's SmartDLP module. It's seamless, and the administrative overhead is low. We aren't a very sophisticated operation. We just want to reduce our exposure, so we find ThreatCloud helpful. Avanan's acquisition by Check Point was beneficial for them."

"Email encryption enhances end to end security of any data before it passes through the networking system."

"Email inspection has saved many employees from spam attacks and viruses from unauthorized sources."

"Avanan has been an everlasting security solution for our email and messaging applications."

"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."

"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."

"We have highly benefited from this platform since we deployed it, as it has provided reliable security to our email infrastructure and developed a secure working environment."

More Avanan pros

"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."

"The good part is that you don't have to configure it, which is very convenient."

"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."

"The insights provided with Microsoft Defender for Office 365 are helpful because it comes with the E5 license, and by default, we can use a lot of capabilities."

"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."

"My experience deploying Microsoft Defender for Office 365 was seamless."

"The initial setup was easy."

"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."

More Microsoft Defender for Office 365 pros

Cons

"The response time for support must be reduced."

"Our customers no longer use Cloudflare because its service is subpar."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"Operating and tuning the product is difficult."

"Feedback could be enhanced."

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."

More Cloudflare One cons

"Since it periodically identifies ordinary emailers as spam or dubious, they may need some AI logic improvement."

"The response to new threats is sometimes slow and can lead to data compromise."

"Integration with various SaaS offerings, who are leading in the SaaS market. Examples include: SNOW (ServiceNow), Salesforce.com"

"There are times when we have false positives."

"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."

"The customer service team could come up with clear tutorials on how to use this platform to help new teams."

"They should come up with a mobile application so that it can be more flexible."

"The user experience must be improved."

More Avanan cons

"Configuration requires going to a lot of places rather than just accessing one tab."

"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."

"I was looking for some advanced features, like if I would receive an email that contains a legitimate file type, but the content is malicious, how I can protect against that?"

"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."

"There's room for improvement regarding the time frame for retrieving emails."

"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."

"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."

More Microsoft Defender for Office 365 cons

Pricing and Cost Advice

"The solution is not that expensive."

"Cloudflare Zero Trust Platform's pricing is good."

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"The solution's pricing lacks transparency."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The prices are slightly expensive."

"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."

"The product is not the cheapest in the market."

"The pricing of Avanan is reasonable."

"Good pricing arrangement as an SaaS offering."

"Avanan’s price is comparable to Barracuda."

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."

"The pricing has become expensive."

"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."

"The license is expensive because the cost is based on the number of users."

"The product is expensive."

"From the pricing point of view, like any other product in the market, there is scope for negotiation."

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."

"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
