    Cloudflare has features as a CDN/Gateway/Reverse Proxy that simply don't exist in other solutions. Having so many capabilities under a single platform, with solid support and high uptime, has been essential. I would recommend it for hobby projects all the way to enterprise scale. There's a lot of push around AI and workers. Some feel like Cloudflare is following the hype. But after reading a lot about the new features, a decent amount of them has real value.

    It is an excellent tool for scanning servers, workstations, and network devices to identify missing patches and misconfiguration; we regularly use it to confirm patch effectiveness after the update; it also helps us for preparing audits such as iso 27001, and regulatory requirements, it also helps us to identify open ports and services that violate security.

    Pros
    Cloudflare
    • The best part is the content delivery network. Cloudflare has a large network of data centres around the world that helps cache and delivers content quickly to our customers.
    • Cloudflare offers us with a fast and reliable DNS service and with the world class features such as Cloudflare workers, SSL verification, certificate management and web application firewall. When all of these are combined together, it provides very strict security for our organization.
    • One of the most important feature that we use is the analytics and threat detection. It provides us with the real time insights of all the threats originating from multiple locations and landing on our websites.

    • Nessus is best at performing vulnerability scans, in fact, it gives findings and moreover accurate findings of the assessments. It does not do penetration testing or exploit the vulnerabilities because it is concerned about scanning the systems/applications.
    • In fact, Nessus has multiple profiles/policies to perform different types of scans such as, scans oriented for PCI-DSS, malware scans, web application scans, bad shell shock detection scan to name a few.
    • Nessus has the ability to classify the vulnerabilities into risk-based categories from critical to even informational which I think is one of the things that separates Nessus from other vulnerability scanners.

    Cons
    Cloudflare
    • In some cases, using Cloudflare can actually lead to slower website speeds if the network is congested or if the website's traffic is particularly heavy.
    • Some website owners may find that the level of customization offered by Cloudflare is limited, especially in comparison to other solutions.
    • While Cloudflare is easy to set up and manage, it may be too complex for users who are not familiar with web technologies.

    • The tool has lots of options for setting up before scanning any device, this methodology could be simplified further with default configuration for various devices predefined, anyhow we can use this technique by making use of policies.
    • For advanced users we cannot disable the plugins inside the plugin groups, we can enable the whole set of plugins at a time, for few hundreds its ok, but thousands of plugins are of waste of resource and time.

    Usability
    Cloudflare
    Everything is extremely concise and all settings apply immediately and take effect globally. There is no reason to explicitly plan/think in terms of individual regions as one would have to traditional cloud offerings (AWS, OCI, Azure). All Cloudflare products integrate seamless as part of a single pipeline that executes from request to response.

    Tenable Nessus is a great product and provides a lot of value, but it is difficult to set up and use and the amount of data it generates can be overwhelming. It does help us prioritize based on the severity of the detection, however there are sometimes mitigating factors that we have implemented that Nessus does not account for, which causes lots of noise in the reports.

    While I have had good support in the past from Cloudflare's technical support team, I have had some terrible experiences with billing support. I have had multiple tickets sent to their billing support that I will never receive a reply to for over a month. When I finally do get a reply, it has been an automated email that never gives me an answer to my question.

    Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

    Return on Investment
    Cloudflare
    • Immediate ROI on Registrar and DNS hosting while giving a single plane of glass to managing both with domain registrations at cost, and no cost DNS hosting
    • WAF helped us move at risk servers/applications into a protected state allowing us to perform remediations at a measured pace and get them done right instead of band aide solutions.
    • CDN proxying increase the speed of our website while simultaneously reducing server load.
    • DMARC management and report interpretation allow use to identify weak points in our email systems, remediate and move to stricter policies without significantly increasing staff time spent managing it.

    • Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
    • The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
    • Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.
