Ken – Security Guy, Entrepreneur and Investor

Vivian is easily the most knowledgeable person I have ever worked with. Not only is he knowledgeable of security, he is also highly knowledgeable in the Online Gaming industry which was an important factor for us hiring him. He is always on-time, always understands exactly what we need and never leaves a hard job undone. I would highly recommend Vivian at any opportunity for security consultancy for any organisation.

Stefan - Security Consultant

I have worked on a number of mutual projects with Vivian over the years and have always found him to be a really genuine person to work with. He has an in-depth knowledge of the payments and payment compliance ecosystem, which elevates his persona to a trusted advisor (our paths crossed specifically on PCI DSS projects).

Miguel - Security Auditor

I have worked with Vivian in two different companies. Vivian is a patient listener, but also a skilled negotiator. He has empathy to understand the business constraints and offer solutions based on those requirements. With his calm demeanour, he develops good long-lasting relationships with his clients.

Francesco – CISO

I met Vivian back several years ago when we first collaborated on a PCI DSS project for an International Financial Institution. Vivian's knowledge in the area of the payments industry is unparalleled.

Victor – International Retail Group

When you first meet Vivian the first impression is that you can work and trust this guy. Then as the relationship builds you realise not only where your initial views correct but underestimated. Vivian is a rare individual who puts the customer first and only delivers solutions which are both relevant and appropriate for our needs. Vivian's persistence to fully understand the challenges I faced as a potential customer is commended and consequently, I did business with Vivian in two different organisations with excellent results. I can only highly recommend Vivian.

Peter – Consultant 

It doesn't matter how much advice you give someone, if they don't act on it. Vivian is one of those people who has a gift of knowing exactly how to do the right thing. Vivian is never one to sell something, without first finding out the real benefit to the customer. In fact Vivian is such a master at understanding clients that they end up buying from him, because he has helped them understand the true value of the relationship. So if you intend to become a customer of Vivians, you know you will be in a safe pair of hands.
