People from Stickman looked very professional from our first touch. Their flexibility to satisfy customer needs and delivery oriented approach make them natural choice for SumUp as Penetration Test providers. In the process of our work together Stickman confirmed my conviction that we made the right choice. We got continuous updates on the progress of their work and feedback with practical recommendations about areas which need improvement. Overall work was so smooth that now I feel like we worked together from many years but in fact it was our first time doing business together.
