Some more than common SE tools are your very basic HID tools, I can load up a payload into a USB stick and leave it somewhere for relatively low cost, and just by adjusting the timing or process of the payload a little I can bypass even the more advanced endpoints since they all run on an algorithm. With what people post on the internet these days it's not hard to learn their schedule and plan to deliver said USB or other HID directly to them. Most computers are preset to automatically trust any device that is being plugged in and most enterprises don't consider this as a necessary safety precaution since if their mouse or keyboard stops working they can be expected to just use another one.

Your creativity. A little story to illustrate. One day, my lead pentester and his right arm got stuck in a hotel for some days. They challenged themselves to hack the hotel without any electronic device, just with what was in the bedroom. And they succeeded. They used the TV remote to test some SQL injections in the VOD search engine, found some, and then remapped all porn movies on Disney ones. Rocco and the hostesses would give you White snow... Ironic no? Creativity is your number one tool. Think differently; this is the very essence of hacking.

In essence, Pentera emerges as the quintessential choice for penetration testing, offering a holistic approach to identifying vulnerabilities in your network infrastructure, web applications, wireless networks, and even human factors.
