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
7.5
Digital Guardian improved data protection, reduced breach risks, ensured compliance, saved money, and enhanced security and operational efficiency.
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
6.6
Digital Guardian offers 24/7 global customer support with quick issue resolution, though some users face delays and varying service quality.
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
7.8
Digital Guardian is scalable, handling hundreds to thousands of users efficiently, with unified server management and straightforward licensing.
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
7.4
Digital Guardian is reliable and performs well, though some users face challenges with agent stability requiring regular updates and support.
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.
Digital Guardian needs better Linux/Mac support, stability, compatibility updates, multilingual dictionaries, pre-sales support, partner program, and technical support.
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.
The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client.
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.
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.
Digital Guardian excels in data protection, boasting extensive features, stability, scalability, ease of setup, and high user satisfaction.
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.
Sandeep Jopat - PeerSpot reviewer
Highly customizable, helpful support, and multiple modules available
Digital Guardian is generally considered stable, with its robust data loss prevention capabilities being highly valued by organizations. However, as with any complex software solution, there may be occasional challenges in terms of compatibility with certain operating systems or applications. In such cases, it may be necessary to modify settings or entries within Digital Guardian to ensure optimal performance. Overall, Digital Guardian is a stable solution that can be highly customized to meet the specific needs and requirements of organizations. As with any software solution, regular maintenance and support from a team of experts is necessary to ensure optimal performance and stability.
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.
