Tenable Security Center optimizes resources, enhances security, and reduces costs with improved compliance, visibility, and efficient management.

Cloudflare's support is praised for responsiveness, though non-paying users and regions without local offices face challenges.
Sentiment score
7.3
Tenable Security Center's support is generally effective with praised premium service, though initial and international support need improvement.
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.
Longer response times and less thorough assistance.
 

Scalability Issues

8.2
Cloudflare efficiently handles increased traffic and growth, offering scalability, robust network performance, and seamless expansion for enterprises.
Sentiment score
8.2
Tenable Security Center is praised for its high scalability, easily managing numerous assets and users while supporting future growth.
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.
I can scale it extensively with the use of agents, allowing scanning in restrictive environments and loosely connected devices.
Scalability is a bit limited with Tenable Security Center.

The stability of the solution is outstanding.
 

Room For Improvement

Cloudflare needs analytics, threat insights, improved support, user-friendly dashboards, and simplified pricing, with consistent caching and security features.
Tenable Security Center struggles with customization, integration, performance, and support, needing improved UI, assessment, and management capabilities.
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.
It's important for Tenable to catch up on testing capabilities that are present in solutions like Qualys.
The reports and plugins for reports and scans could benefit from enhancements.
Translating reports into European languages is especially relevant in Central Eastern Europe, where clients often require reports in local languages.
 

Setup Cost

Cloudflare offers flexible pricing with plans for small businesses to enterprises, balancing cost with comprehensive features and protection.
Tenable Security Center offers comprehensive but expensive asset-based pricing, with complexity impacting setup and licensing, especially for smaller enterprises.
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.
The product is somewhat pricey, reflecting its valuable features and status as a high-quality solution in the vulnerability management market.
Tenable Security Center is quite expensive, particularly for the CEE region, causing us to lose cases due to its pricing.
The cost of Tenable Security Center is reasonable for our company.
 

Valuable Features

Cloudflare offers caching, DDoS protection, and CDN services, enhancing website speed and security with intuitive interface and global reach.
Tenable Security Center excels in vulnerability scanning, customizable policies, and integrations, with user-friendly UI and predictive prioritization.
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.
Tenable Security Center provides an overall score of vulnerabilities, comparing an organization with others in the same industry.
The most effective feature of Tenable Security Center for detecting vulnerabilities is its capability for critical mapping.
The most valuable features of Tenable Security Center for my clients are Vulnerability Priority Rating (VPR) and Asset Criticality Scoring.

Featured Reviews

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.
OndrejKOVAC - PeerSpot reviewer
Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.
