Best paid & free vulnerability assessment tools for software teams

Table Of Contents

Adding good vulnerability testing 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.

In this article I've only considered web app vulnerability scanning tools. Mobile app or IoT vulnerability testing tools are at this stage only designed to be used by cybersecurity experts and cannot reliably be integrated into you a DevOps software deployment pipeline.

So now, 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 tool can help you with all your vulnerability management needs.

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

APIs rule the world irrespective of whether you're building a modern application or trying engaged in a digital transformations of legacy applications.

API vulnerability scanners not only help you with scanning vulnerabilities in your REST, SOAP and GraphQL APIs, but the best vulnerability scanners for APIs also:

• Help you discover all API endpoints
• Make it easy to produce configuration files in OpenAPI or Swagger format
• Perform automated vulnerabiilty assessment on your APIs daily without having to employ someone to operate the scanning tool.
• Help your minimize the chances of shadow APIs creeping into prod.
• Work alongside a powerful web vulnerability scanner to put your application security on autopilot, without being forced to hire expensive security experts.

Good API vulnerability assessment tools work like a baseline security analyzer and give you results that you can rely on and benchmark whether your application is cloud-based or on premises.

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:

• Poorly configured IAM policies.

• Publicly exposed resources that should be very private (think S3/Blob buckets).

• Configuration compliance issues that is used in compliance reporting for ISO27001 certification or SOC2 certification.

• Other best-practice cloud security controls.

Can all vulnerability scanning tools find security vulnerabilities in software?

The short answer is no - not all vulnerability assessment scanning 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 scanning 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:

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.

The good news is that most of these security issues can be prevented with a regulat vulnerability assessment, in between your periodic web application penetration tests.

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 run a web 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 scanning tools don't charge you for peforming more scans. So why not do more scans rather than fewer scans?

8 factors that decide the best software vulnerability assessment scanning tools

Even systems that seem secure have vulnerabilities.

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 API, which means that a vulnerability assessment from such tools could lead to many false positives.

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 vulnerability assessment 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 ever use it to run vulnerability scans.

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. Unfortunately, this is where many open source app scanning tools fall short with their vulnerability tests.

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

   False positives can be overwhelming to a network configuration manager when filtering false positives. An accurate vulnerability scanning tool can avoid such pointless vulnerability analysis tasks and save your team tons of time.
