Supporting ethical workplaces

We are a global network of experts in investigations, safeguarding, compliance, governance, security, and anti-corruption.

Let's keep it simple. If you've got people, you are vulnerable to human risk factors

People are capable of remarkable things, but we’re also fallible. It’s a simple truth that’s never been so clearly visible in our global humanitarian organisations, international businesses, financial institutions and governing bodies.

OSACO Group safeguards your organisation from the threats and liabilities of Human Risk factors



Human risk factors can, and do, occur anywhere and in any organisation. They range from fraud, corruption and financial crime, to sexual exploitationand abuse, and safeguarding failures.

OSACO Group helps organisations of all kinds to anticipate, identify and combat unacceptable conduct by those who work within them and/or on their behalf.


We provide expert investigators and other specialists to predict, prevent and respond to your human risk factors. We are agile, responsive and highly capable

When we engage with you, you get our full and undivided attention. We know that a personalised service drives better outcomes. You will have a top team and a dedicated manager.



Imagine turning your organisational threats into advantages. Mastering risk builds confidence in your organisation, creating customer and societal trust.

The hard truth is that poor risk management severely impacts your organisational goals, funding, revenue and profit streams. This is something you cannot afford.
