Best application vulnerability assessment tools for software companies (paid & free)

Table Of Contents

    Adding good vulnerability assessment tools or virtual app scanning for your software team has become as important as your git repository or your ticket management system.

    So the big questions are, which one will work for your software development:

    1. Without creating extra delays in your application delivery schedule; and

    2. Without creating extra costs related to managing a new tool?

    Naturally, costs (or philosophical considerations) might compel you to choose the open source path.

    But then you're at the mercy of the expedience of community members to fix bugs and release new features.

    You might end up building a whole team in-house to support the open source tool of your choice, which, one would think, defeats the purpose of going open source in the first place?

    A commercial vulnerability assessment tool comes with lots of benefits but may also have some element of "lock-in," which might trouble you, among other aspects of having to deal with a new vendor.

    First, let's start with the different types of application vulnerability assessment tools that are available to you.

    What are the different types of vulnerability scanners available?

    The biggest misconception with vulnerability scanners is that people assume that one scanner can do all types of scans.

    Let me debunk this myth for you: a network vulnerability detection tool like a web application firewall (WAF) or endpoint security tool cannot help you find and fix vulnerabilities in your web applications and APIs, despite their claims.

    Just like a surgeon has different scalpels for different surgeries, you need different scanning tools depending on what you are scanning.

    Web application vulnerability scanners

    Application vulnerability scanners automatically scan web applications and web servers to find OWASP Top 10 vulnerabilities like SQL injection, insecure configurations in your server, cross-scripting and others.

    The best web application vulnerability scanning tools log into your application to scan behind the login.

    This is important because we know that 93% of your vulnerabilities are found behind the login.

    API vulnerability scanner

    API security testing ensures business data packets that move between two software applications and ip addresses are secure.

    When you perform API vulnerability analysis using API scanning tools, you aim to secure data packets in transit using HTTPS. This is a unique challenge that API vulnerability scanners solve.

    The vulnerability disclosure in virtual and private networks will also protect your system from issues like SQL injection and cross-site scripting.

    Network vulnerability scanners

    When performing this type of vulnerability management you can assess your wired and WiFi network security controls and network appliances like routers and firewalls.

    They also help to keep out unauthorized devices from a business network.

    When you perform such network vulnerability tests, you can identify current devices and users in your network and take inventory of your network elements.

    Cloud platform vulnerability scanning tools

    Most businesses are shifting to a cloud-based model and using cloud infrastructure for their applications and APIs because of higher flexibility and scalability.

    This cloud infrastructure also needs to be secured. That's why vulnerability management using cloud platform vulnerability scanning tools will help you find and fix security threats like:

    Can all vulnerability scanning tools find security vulnerabilities in software?

    The short answer is no - not all vulnerability assessment tools can find every security vulnerability in the software.

    And let's be honest if any tool claimed to do so, it would be like a chef claiming they can make a perfectly cooked steak every time - sounds too good to be true, right?

    While some vulnerability testing tools are designed specifically to scan for vulnerabilities in web applications and APIs, others only perform network vulnerability scanning as I explained earlier.

    Network vulnerability scanners are typically used to detect and assess your WiFi security and vulnerabilities in your network infrastructure, such as firewalls, routers, and servers. They cannot log in to your web application or authenticate with your APIs and find vulnerabilities in your software as a logged-in user.

    Remember the infamous Equifax data breach in 2017?

    Well, it turns out that the vulnerability that led to the breach was actually known and could have been prevented if the right vulnerability scanner had been used.

    What are the benefits of using vulnerability assessment tools during software development?

    Let me ask you this: is it better to stay fit and in the correct weight range throughout your life or only after your doctor tells you that you're overweight and at risk of serious diseases?

    Similarly, if you run an application security process as an afterthought, you will be left with this problem:

    A complete vulnerability assessment tool can help you find and fix vulnerabilities early to save money

    It'll take your team longer to untangle the vulnerabilities and they'll have to rewrite more code. All of this costs more time, therefore money.

    It also leaves your application vulnerable for longer to many OWASP Top 10 vulnerabilities:

    Cross-Site Scripting (XSS)

    XSS occurs when a hacker loads malicious code in a web application from an external and unauthorized server.

    Users of web applications compromised by this won't even know what's happening and can not only expose sensitive data but also ruin your app's user experience.

    Code Injection

    when there are missing updates or the web applications are vulnerable attackers can execute harmful codes. This is known as code injection which enables an attacker to take control of a business system once a user executes the code.

    For example, a hacker can inject an SQL statement that always directs users to a specific table. This can allow access all customer-sensitive information and spoof identities in virtual environments.

    Executing Arbitrary Commands

    Attackers submit malicious input to a system that will execute arbitrary commands with the aim of taking control of an application.

    After executing these commands they perform harmful activities like installing malware or deleting files that will affect everything from operating systems to APIs to databases and eventually affect business operations.

    Buffer Overflow

    A buffer overflow allows attackers to execute malicious code when a program tries to store excess data in the memory. The excess data can overwrite some parts of the memory and execute a harmful code.

    For example, if you input data that's 10 bytes in a memory space that's only 8 bytes long there will be an overflow of 2 bytes. Such security risks can be difficult to handle but with the right mitigation techniques, you can avoid them.

    Password Vulnerabilities

    using weak passwords compromises critical business assets. When employees or team members use default passwords or passwords that hackers can quickly guess, it leaves systems vulnerable.

    Lack of Encryption, Authorization, and Authentication

    When you store or transmit data without encryption it poses a risk. Malicious actors can intercept such data or steal it from the database.

    Another method hackers use is exploiting authorization and authentication weaknesses in systems. For example, poor access control or abusing session privileges can make web servers and other web applications vulnerable to attacks.

    How application vulnerability scanning tools identify and mitigate risks

    Application vulnerability scanning employs a combination of techniques such as static analysis, dynamic analysis, and pattern matching, to uncover vulnerabilities.

    For instance, a complete vulnerability assessment tool like Cyber Chief starts by crawling the application, exploring various paths and functionalities. During this process, it collects information about inputs, outputs, and potential attack vectors.

    Next, the tool performs dynamic analysis by interacting with the application and simulating various attacks. It sends crafted requests to inputs, monitors the responses, and analyzes the behavior of the application under different scenarios. By doing so, it can detect vulnerabilities like cross-site scripting (XSS), SQL injection, or insecure access controls.

    Additionally, static vulnerability scanning tools leverage pattern matching techniques to compare application components against known vulnerabilities, such as outdated libraries or frameworks. They reference comprehensive vulnerability databases, such as the Common Vulnerabilities and Exposures (CVE) list, to identify potential matches.

    By combining these techniques, application vulnerability scanning tools can effectively uncover security gaps in an application, helping software engineering managers proactively address them before they are exploited by malicious actors.

    How often should I be using a vulnerability scanner on my web applications and APIs?

    Well, if your web application is actively developed by a team of developers with new code being pushed daily then you should be doing a daily automated vulnerability assessment.

    If your application is not actively enhanced or altered, you can afford a vulnerability management structure that happens more irregularly.

    But the real point is that the best vulnerability assessment tools don't charge you for peforming more scans. So why not do more scans rather than fewer scans?

    8 factors to consider for the best software vulnerability assessment scanning tools

    Even systems that seem secure have vulnerabilities.

    SQL injection attacks can be prevented with timely vulnerability assessments

    Some of these vulnerabilities are obvious, and you can fix them quickly while others are serious issues and need more complex security patches.

    1. Type of vulnerabilities: The tool should be able to detect all OWASP Top 10 and SANS CWE 25 vulnerabilities.

      Don't be fooled by lesser tools that advertise "we test for 100,000 vulnerabilities" because most of them don't even apply to cloud applications and APIs.

    2. Scope of testing: The tool should be able to test the entire software stack, including front-end, back-end, and middleware components, to ensure comprehensive testing coverage.

    3. Integration capabilities: The tool should be able to integrate with other tools and systems used in the organization, such as continuous integration/continuous delivery (CI/CD) pipelines, bug tracking systems, and security information and event management (SIEM) tools.

    4. Reporting and analytics: The tool should provide comprehensive reports and analytics that enable software engineering managers to understand the severity of vulnerabilities and prioritize remediation efforts.

    5. Ease of use: The tool should be user-friendly and easy to set up, configure, and use, even for non-security experts. An easy-to-use vulnerability scanner means you will take less time to identify and correct security vulnerabilities.

      It also means the vulnerability assessment tool does not require you to have extensive knowledge or training before using it,.

    6. Security patches: The vulnerability scanner that's right for your team is one that gives your software developers on-the-job coaching about how to patch vulnerabilities.

      This type of web application vulnerability tool will not only help you upgrade your security process but also save you a truckload of money on formal security training.

    7. Training and experience: Any vulnerability scanner that requires your software team to attend a training session to learn how to use it is probably not a good use of your time or money.

      Your devs have enough to do. Why burden them with having to sit through training to learn a new tool? They'll start to resent it and probably won't even use it.

    8. Support and documentation: The tool vendor should provide adequate support and documentation to help software engineering managers set up and use the tool effectively.

    9. Accuracy and false positive rates: The tool should have a high accuracy rate in detecting vulnerabilities while minimizing false positives to avoid wasting time on unnecessary remediation efforts.

      False positives can be overwhelming to a network configuration manager when filtering false positives. An accurate vulnerability scanning tool can avoid such issues and save time.
