Q&A Highlights
Question: F5 vs. Imperva WAF?
Answer: Firstly, implementing WAF is an excellent decision. With application logic and date being at the core of the technology stack value, WAF is the most reasonable place to monitor application traffic and defend from hacker's attacks. I have recently published a blog post on the issues one needs to consider when selecting a WAF. In addition, here are some thoughts on the specific questions you are asking Both F5 and Imperva are excellent WAF offerings with long track records and both will likely do a good job detecting known OWASP 10 threats. That said, both F5 and iMPERVA are signature based WAF technologies. For zero-day threats for which no signatures exist, no protection is provided until someone creates a signature and is able to write a rule for protection. For more agile 0 day threat protection you may want to consider a machine-learning driven solution which creates application-specific security rules automatically. As far as administration is concerned, F5 natively integrates with the application delivery system (ADC) which makes deployment & routing administration easier. The other aspect of the administration is addressing false positivies that WAF generates to avoid interfering with normal application operations. Because of false positives, many of the iMPERVA and F5 customers deploy these solutions in non-blocking mode with the main goal of providing visibility. Deciding which detected incidents require action is what requires the bulk of administration by security experts with deep knowledge of web application code and web application security. On the subject of costs and benefits, a lot of the benefits of the traditional WAF systems are centered around compliance. These are often hard to quantify but are the cost of doing business. Other than that, costs of WAF, as with most security solution, come less from the cost of the licenses and more from the cost of administering the solution and putting in integrations with other systems to derive real benefits. Again, machine learning-based system can help here with an automated and continuous approach. Essentially such system performs the jobs of a Red Team and a Blue Team in AI. Overall, both iMPERVA and F5 are good solutions, but before making your final decision consider if you want to go with a signature-based WAF or deploy a machine-learning driven solution like Wallarm.

"Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient.""Some maintenance must be performed by our IT team.""The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information.""Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution.""The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side.""Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers.""We had an issue when securing the web applications for DDoS protection.""Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."

    In order to achieve the core objective of a WAF (Web Application Firewall) definitely you are focusing on the External Facing application, for external facing application IMPERVA INCAPSULA has a high ratio of payload collector which identify and capture the payload entered by the malicious user without tempering the original content of a Payload. Once the paylaod has been captured, you can easily block the content appeared in the payload and this can be done automatically as well. Another good feature of this WAF is even if a malicious user is using NAT environment or Proxy based environment it will show the A.S (autonomous System) of the last region and also in some cases reveals the NAT IP Address from where the payload is actually captured.

    1. F5 has a protection to L7, but dont work as a sand-box.2. F5 has a nice GUI with many options to understand whats happen in real-time3. F5 isn't cheap but is cheaper than Imperva.

    I don’t know anything about Imperva WAFs, but I can tell you that F5 makes security a high priority, and they respond quickly to threats with either recommendations on things to change or updates. Plus, F5’s products are very intuitive and have GUIs that make administration a breeze, as well as a large support community and KB to consult for command line stuff or more complicated administration via the GUI. F5 products do cost a lot, though, and I would say that’s the main drawback.

    You'll need to weigh your specific requirements and ideally POC both solutions. In our case, after having used both F5 and Imperva WAF solutions we found Imperva to be a more comprehensive fit for our needs.

    One of the primary issues with the F5 ASM solution was the performance implications on the load balancers for which it was enabled. If you have the option and budget, I'd suggest a review of Silverline vs. Incapsula to reduce the maintenance and administration overhead. This would have removed the performance issue from the equation for us.

    Hi There;

    Yes I can help !

    That's a really good question as the answer is always 'it depends'.

    There's really no obvious vendor answer between Imperva and F5 - more pros and cons that you need to match to your use case checklist so I can throw out a fairly standard scouting report of the two and hopefully you'll spot which one more suits your WAF needs.

    Ps The first question I'd ask as a precursor is 'why do you need a specific WAF ?

    Many UTM / NGFW vendors (eg the Fortinet, Palo Alto, Cisco, Checkpoint best of breed quartet) roll WAF as a standard service / feature and it's usually 'good enough'.

    Presuming you already have firewalls and a subset of their UTM sheet turned on - eg IPS, IDS, VPN,.....simply turn on WAF as the quickest and cheapest route to done.

    Second question is if starting from scratch why not look more at future state SDN solution like say Big Switch that offers a more flexible security policy workflow orchestration and automation approach to WAF and other services in your data scrubbing food chain.

    Back to F5 vs Imperva

    F5 Pros
    Cadillac - feature rich
    - highly programable, flexible
    - central APM suite extends to WAF
    - good for complex rules/policy
    - load balancing kingpin

    F5 Cons
    Overkill. - complicated to set up/maintain
    - high priced/skilled PS work
    - takes over your ecosystem and doesn't integrate well with others
    - expensive

    Imperva Pros
    Integrated Knitting - plays well in sandbox
    - good enough features for price
    - easier / cheaper

    Imperva Cons - service play vs product
    - more about ps team than polished product
    - unclear product roadmap, corporate longevity (ie buy out target)
    - lots of custom code, scripts to maintain in knitting

    There you go - it's a case of premium beer vs brew your own so depending on whether you are Fortune 500 or SME - budget vs on hand security design talent - that's dictates your direction on vendor vs any sort of Gartner MQ comparison....(IMHO)

    And please see questions 1 and 2....I see WAF as not existing in a couple of years - either absorbed as a commodity by UTM space or greatly improved by SDN space


    it_user685098 - PeerSpot reviewerit_user685098 (Head of Business Development at Loadbalancer.org)

    Imperva are a market leading WAF vendor, whilst F5 are a market leading load balancer (ADC) vendor. That said, the F5 WAF is awesome, and will offer all the security functionality you're ever likely to need. My advice would be to do some homework on price, as both options will provide an intuitive interface and offer excellent threat response times.

    it_user444444 - PeerSpot reviewerit_user444444 (User)

    We really have experience in WAF solutions, but our main Partner is Akamai KSD(Kona Site Defender) and in our opinion is the more completed solution in these market

    About F5 and Imperva solution I can’t answer those questions.

    The answers are not so simply because seems to be.
    In very draft – for the moment I’ ll be back in details later – my answers :

    1) Security  Both are very good solutions, with a huge amount of successful cases. The “response” is something that we can discuss it. We have cases with the one is better than the other and reverse. If you discussing about the response when you are opening a ticket for example, our experience says F5.
    2) Depends on what experience the engineer has. I mean is not a crystal clear to say one or the other. The ways that F5 works is by far more powerful than IMPERVA.
    3) Well, if we would have this discussion 2 years before the answer would be IMPERVA. BUT F5 made a great job these two years, with a huge investment regarding the Cloud and also the functionality. The disadvantage is scaling license of F5 because the F5 upgrades the FQDNs in 5. On the other side IMPERVA upgrades in 1. Another disadvantage is that F5 has no less than 50 MBps license (regarding the SilverLine solution), when IMPERVA starts from 1MBps

    PLEASE SEE BELOW some details :

    HTTP protocol security
    – Header name with no header value: Specifies that the system checks requests for valueless header names, which are considered illegal.
    – Several Content-Length headers: Specifies that the system examines each request to see whether it has more than one content-length header, which is considered illegal.
    – Chunked request with Content-Length header: Specifies that the system examines chunked requests for a content-length header, which should not be permitted.
    – Null in request headers: Specifies that the system inspects request headers to see whether they contain a Null character, which is not allowed.
    – Content length should be a positive number: Specifies that the system examines requests to see whether their content length value is greater than zero.
    – Bad HTTP version: Specifies that the system inspects requests to see whether they request information from a client using a legal HTTP protocol version number (0.9 or higher).
    – Host header contains IP address: Specifies that the system verifies that the request’s host header value is not an IP address.
    – Unparsable request content: Specifies that the system examines requests for content that the system cannot parse, which is not permitted.
    – Bad host header value: Specifies that the system inspects requests to see whether they contain a non RFC compliant header value.
    – Check maximum number of headers: Specifies, when checked (enabled), that the system compares the number of headers in the requests against the maximum number you specify.
    – Request Checks: Examine lengths (URL, Query strings, Requests, Posts etc), allowed methods (get, put, post etc), disallowed files types, mandatory headers.

    CSRF Protection
    Cross-site request forgery (CSRF) attacks work by forcing the user to run unwanted actions on a website in which the user is currently authenticated.
    For example, an attacker may iframe code into a web object that forces the user to request a specific URL without the user's knowledge.
    When you enable the CSRF Protection feature in the security policy, the BIG-IP ASM system differentiates between legal requests and forged requests by generating and storing a unique session token in the BIG-IP ASM cookie. The BIG-IP ASM system then verifies the ingress requests, and attempts to match the HTTP parameter value with the BIG-IP ASM cookie value in the request.

    Web Scraping
    Web scraping is a technique for extracting information from web sites that often uses automated programs, or bots (short for web robots), opening many sessions, or initiating many transactions. You can configure Application Security Manager™ (ASM) to detect and prevent various web scraping activities on the web sites that it is protecting.

    Data Guard
    In some web applications, a response may contain sensitive user information, such as credit card numbers or social security numbers (U.S. only). The Data Guard feature can prevent responses from exposing sensitive information by masking the data (this is also known as response scrubbing).
    Note: When you mask the data, the system replaces the sensitive data with asterisks (****). F5 Networks recommends that you enable this setting especially when the security policy enforcement mode is transparent. Otherwise, when the system returns a response, sensitive data could be exposed to the client.
    Using Data Guard, you can configure custom patterns using PCRE regular expressions to protect other forms of sensitive information, and indicate exception patterns not to consider sensitive. You can also specify which URLs you want the system to examine for sensitive data.
    The system can examine the content of responses for specific types of files that you do not want to be returned to users, such as ELF binary files or Microsoft Word documents. File content checking causes the system to examine responses for the file content types you select, and to block sensitive file content (depending on the blocking modes), but it does not mask the sensitive file content.

    Layer 7 DDoS Protection

    – Proactive Bot Defense during attacks (this feature requires JavaScript support from the browsers): defense against bot attacks by detecting and stopping them before the attacks start to grow, by performing the following:
    • The system sends a client-side JavaScript challenge to the browser.
    • If the challenge is met, the system adds a cookie to the second request. This cookie is active until the session ends, and the system does not add any more cookies to further requests during that session.
    • The system drops requests sent by browsers that do not answer the system’s initial JavaScript challenge, assuming they are bots that do not support JavaScript.

    – Bot Signatures: Allow requests from legitimate (benign) bots and malicious bots to bypass the proactive bot defense and give them visibility in the reports.

    – TPS-based DoS Detection. Configures the detection of DoS attacks based on high volume of incoming traffic.

    – Stress-based DoS Detection. The system automatically detects an increase in server stress and mitigate DoS attacks causing it.

    – Client Side Integrity: Τhe system determines whether the client is a legal browser or an illegal script by sending a JavaScript challenge to each new session request from the detected IP address, and waiting for a response. (Legal browsers are able to respond, while illegal scripts cannot.) Client Side Integrity can be enabled in several attack types whenever TPS is suspiciously increased.

    – Behavioral protection: Enables the system to automatically detect Layer 7 DoS attacks using behavioral data, characterize the offending traffic, and automatically mitigate the offending traffic.

    – Heavy URLs protection: This feature allows protecting Heavy URLs during DoS attacks. Heavy URLs are a small number of site URLs that might consume considerable server resources per request, even with a low TPS count. Heavy URLs respond with low latency most of the time, but may easily reach high latency under specific conditions. Heavy URLs are not necessarily heavy all the time, but are potentially heavy, especially during DoS attacks.

    – Brute Force Protection: The system considers it to be an attack if either the detection interval exceeds the history interval by a relative amount specified on this screen, or the failed logon rate reaches a specific number specified on this screen

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Imperva DDoS users.

    PeerSpot user, Etienne W., CDN & Cybersecurity Engineer - Web performance & security at CDN Tech / Ecritel, says, “It is a good solution that allows us to protect websites. It is stable, scalable, quick and easy to use.” He goes on to explain, “WAF protection works almost out-of-the-box. The Anti-DDoS mitigation in less than 1s, I saw it many times in production, I can say it works. CDN has high performances, and the Smart Caching mode is really "smart" (you can do some efficient caching even if you're not a specialist). Its unique interface for managing security performance and ease of use are the most valuable features of this solution."

    An IT Senior Manager at an outsourcing company mentions, “The most valuable features are DDoS protection. The Incapsula [Imperva DDoS] environment helps us monitor all the web activity. All the web activity is passed through their WAF cloud services, then that can help us to monitor those activities. That can help protect against DDoS hacking.”

    Another PeerSpot reviewer, Ben D., Sales Executive at EVVO LABS, comments, "Imperva Incapsula [DDoS] has many valuable features. One, it protects the top 10 OWASP vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."
