Review summaries and opinions

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

ROI

Sentiment score
6.5
Cloudflare enhanced speed, security, and data protection, providing significant ROI and improved operations and client satisfaction for businesses.
Sentiment score
8.4
Avanan improved email security, reduced phishing, increased user trust, enhanced mobile protection, and boosted ROI and revenue growth.
Sentiment score
7.1
The Zscaler Zero Trust Exchange Platform enhances ROI and satisfaction by improving visibility, security, and cost-effectiveness over previous setups.
WordPress security can be tricky, and that's where Cloudflare can be absolutely helpful for small businesses.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
We don't have to purchase many components such as load balancers and proxy servers that were necessary in traditional setups.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is efficient for paying users, but responses can vary in speed and effectiveness for others.
Sentiment score
8.1
Avanan's customer service is highly responsive, professional, and proactive, with excellent communication and extensive support staff knowledge.
Sentiment score
4.8
Zscaler's customer support is generally good but inconsistent, with varied user experiences and ratings from four to ten.
This would help us address issues promptly, especially during unforeseen events like DDoS attacks.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
The key factor is the language in which the support is offered, which, in this case, is in Thai.
Sometimes, support takes time since the solution has some bugs that need fixing.
 

Scalability Issues

Sentiment score
8.1
Cloudflare is praised for seamless scalability, managing enterprise-level traffic efficiently and earning high customer satisfaction during peak events.
Sentiment score
8.2
Avanan integrates with Office 365 and Google, praised for scalability, admin capabilities, and efficient email protection across diverse organizations.
Sentiment score
7.7
Zscaler's Zero Trust Exchange Platform is highly scalable, integrating seamlessly with systems and accommodating varying user needs effortlessly.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
The tool offers very good performance, even during high-traffic periods.
I rate the solution’s scalability an eight out of ten.
 

Stability Issues

Sentiment score
7.6
Cloudflare is widely regarded as stable and reliable, with improvements noted in uptime and performance on higher plans.
Sentiment score
8.5
Avanan is highly praised for its stability, efficiency, security, minimal maintenance, seamless Microsoft 365 integration, and reliable AI-based scanning.
Sentiment score
7.8
Users rate Zscaler Zero Trust Exchange highly for stability, citing minimal downtime and suggesting occasional improvements for certain areas.
For DDoS protection, I would not recommend Cloudflare.
I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
 

Room For Improvement

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
Users feel Avanan needs improvements in Active Directory dependency, email quarantining, AI logic, training, UI, performance, pricing, mobile app, and integrations.
Zscaler needs enhancements in speed, multi-tenant capabilities, compatibility, DLP features, cost, stability, support, and connectivity monitoring.
There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
Cloudflare should add more documentation and pricing to the cloud version.
They might be able to identify if something is missing with Zscaler.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
Avanan provides flexible pricing for Office 365, with straightforward setup and costs between $4 to $8 per user.
Zscaler's pricing varies, becoming more competitive with larger user bases, but additional features can increase overall costs.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
I think they should consider reevaluating the pricing for support, as it can be quite high.
 

Valuable Features

Cloudflare enhances security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
Avanan provides advanced malware and phishing detection, 24/7 cloud protection, easy integration with Microsoft 365, and ensures secure communications.
Zscaler Zero Trust Exchange offers easy management, strong security, seamless connectivity, cloud deployment, threat protection, and AI-driven insights.
The most valuable features of the solution are performance and security.
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
The solution is cloud-based with the latest inspection engines, which I find to be amazing.

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Robert Melendez - PeerSpot reviewer
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.
Sumit Bhanwala - PeerSpot reviewer
Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.
