Now, let's dive into the technicalities of these two providers. Both Secure Blink and Acunetix are well-known web application security tools. However, they do have some differences that set them apart.

This article aims to compare and contrast the features of these two providers.

Heuristic Scanner

For vulnerability detection, both Secure Blink’s Threatspy and Acunetix have their strengths in different areas. Secure Blink’s Threatspy performs both authenticated and unauthenticated scans using an in-house built heuristic scanner that covers a wide range of vulnerabilities, including OWASP Top 10, CWE Top 25, open ports, SSL and DNS, Cors, S3 bucket misconfigurations and Zero Days.To ensure comprehensive coverage of potential vulnerabilities, Secure Blink uses various scanning techniques such as:

  • DAST (Dynamic Application Security Testing)
  • Fuzzing

On the other hand, Acunetix covers a wider range of technologies, including traditional web applications, APIs, While this may seem like an advantage at first glance, it also means that its vulnerability detection may not be as specific or accurate compared to Secure Blink's Threatspy targeted approach toward Web3 applications.

Scan Speed and Efficiency

Secure Blink’s Threatspy surpasses Acunetix in terms of threat scanning speed and efficiency. Secure Blink’s Threatspy offers two types of scans: Light Scan (which runs 7,000 test cases & takes 30-40 mins) and Deep Scan (which runs 25,000 test cases & takes max. 3 hours to complete for both authenticated and unauthenticated scans didn’t get fails in authenticated scan.

In contrast, Acunetix caters to a broader range of web technologies, making its scanning process less targeted and, thus, potentially slower can get fails in authenticated scans

Acunetix also offers incremental scanning capabilities, but it may not be as refined or focused as Secure Blink's Threatspy approach.

Secure Blink’s Threatspy offers both Cloud and On-premise versions catering to the needs of every organization.

Vulnerability Management

One of the standout features of Secure Blink’s Threatspy is its reachability-based prioritization approach in addition to CVSS scoring system. This means that instead of solely relying on a vulnerability's severity, it considers multiple factors such as exploitability rates and proof of exploit. Doing so provides a more accurate prioritization of which vulnerabilities pose the major risk to your system.

On the other hand, Acunetix primarily uses a severity-based prioritization method that looks at a vulnerability's CVSS score. While this can be effective in identifying critical issues, it may not always take into account other important factors, such as potential exploitability and likelihood of attack.

Remediation Approach

Secure Blink stands out for vulnerability remediation with its AI Enabled approach of automating the process as much as possible. Threatspy provide curated stack oriented steps to fix vulnerabilities & expedite remediation process with campaigns, and automatthe ticket creation actions with Playbooks. Custom SLA policies ensure timely notifications for vulnerabilities not getting fix in defined time. This automated approach saves time and effort, ensuring a more efficient remediation process. On the other hand, Acunetix relies heavily on manual efforts for vulnerability remediation. While it does offer detailed reports highlighting vulnerabilities and actionable advice, it still requires manual intervention from developers or security professionals to implement these fixes.

Scanning Methodology

Most traditional web applications and API security solutions employ an agent-based approach for vulnerability detection. However, Secure Blink stands out with its innovative agent-less methodology.

This means it doesn't require installing any software or agent on the target applications, making it lightweight and efficient. Moreover, this method offers several advantages over traditional agent-based solutions. Since installation is unnecessary, Secure Blink can be used in cloud-based deployments without modifying the existing environment. Additionally, it is non-intrusive and does not interfere with the functionality of the target application.

On the other hand, Acunetix relies on an agent-based approach, which requires installing a scanning agent on the web application server. While it offers some benefits like deeper analysis through interaction with applications as a real user and support for mobile app and API security testing, it also introduces overhead to the system.


The platform easily integrates with CI/CD pipelines like GitHub actions, GitLab, Jenkins, Trevis, Bitbucket, Azure pipeline & CircleCI. It also provides Seamless connection with workflow apps like Jira, Trello, Slack, PagerDuty, Splunk etc.

Secure Blink provides seamless security testing in the software development lifecycle. With automated scans at every deployment stage, potential vulnerabilities are identified and remediated early, saving time and resources before hitting to production

Secure Blink's DevSecOps approach enables developers to receive immediate feedback on their code changes and fix issues quickly. This allows for a continuous delivery process without compromising security.

Acunetix has a quite similar integration to CI/CD pipelines, but their scans are not automated and can only be triggered manually. This slows down the development process and leaves room for human error.

API Coverage

Lastly, regarding API security testing coverage, Secure Blink offers a focused approach towards all API definition (REST, SOAP & GraphQl). At the same time, Acunetix also caters only to the Rest and Graphql not SOAP to a wide range of APIs. This difference in coverage may be because Secure Blink's main focus is on API Security

Considering the increasing popularity of blockchain technology and decentralized applications (dApps), Secure Blink's specialized approach is advantageous as it addresses specific vulnerabilities related to these new technologies.


As far as web application and API security is concerned, both Secure Blink and Acunetix offer top-notch solutions. However, their differences do set them apart. If your main concern is securing web based applications or APIs, then Secure Blink is the clear winner due to its specialized focus and automated scanning and remediation techniques.

On the other hand, if you require a more solution that test web apps and APIs only for limited standards web apps and mobile apps, then Acunetix may be a better fit for your organization.

Ultimately, it depends on your specific security needs and vulnerability detection and remediation preferences.
