Protect revenue and reputation

Every organization has two core things to protect – revenue and reputation. Both are directly impacted by a businesses’ ability to build and execute a reliable security, compliance and risk management strategy. Organizations with regulatory requirements must understand the direct impacts that security and compliance management have on their ability to defend and protect both revenue and brand reputation. Wib’s API Pen Testing as a Service (PTaaS) is a key first step to help you achieve both!

What is penetration testing?

Penetration testing (or pen testing) is a security exercise where cybersecurity experts attempt to find and exploit vulnerabilities within the IT infrastructure. API penetration testing focuses its scope on known and unknown API-related vulnerabilities, simulating attacks to identify weaknesses in cyber defenses that could be exploited by attackers – flagging issues for remediation and validating the efficacy of an organizations’ defense mechanisms.

Wib’s Testing Methods

Black Box Testing

In a black box test, you will not provide Wib with any information about your infrastructure other than a URL or IP, or in some cases, just the company name. Our offensive team are tasked with exploiting your infrastructure as if they were an external attacker.

White Box Testing

In a white box test, Wib will receive detailed information about your applications and infrastructure, including a range of credentials to utilize. This test is aimed at providing information on how your security will withstand an attack by an ‘insider’. These tests tend to provide the best results for the time and cost.

Grey Box Testing

In grey box testing, Wib will only have limited information to aid our testing methods. As a mix between Black and White Box Testing, it strikes a balance between depth and efficiency and can offer the simulation of both an insider and external attacker.
