Why Sharing Improves Us

If you're a perfectionist, it's difficult to release a product: Whether that's source code, a pentest report or a blogpost. It's always a work in progress, and never finished.

That's why I like open sourcing code for example, releasing it for everybody to see. Knowing beforehand that the code, your work will be read by others (while you're working on it) forces you to think longer, deeper and harder about the variable names, the structures, function names and coding styles.

I'm the lead pentester for a company where we allow the customer to peek over our shoulder while we're working. The customer can see everything that we try, do and find out during the pentest. This improves the relationship with the customer, as s/he sees what we're doing and even can think along with us.

It also improves the customer satisfaction, as they know exactly what they're getting. And, it improves the mutual respect. Instead of becoming a classical us-versus-them pentest (the pentesters versus the developers), it becomes a 'let's improve the overall security together' exercise.

According to all the positive feedback we're receiving, we're onto something here. A win-win.

Sunlight is not only a great disinfectant, it's also a great energy source for growth.
