People often ask where the name ESA Risk comes from. The simplest answer is this: respect.

But behind that single word lies a story of influence, mentorship and professional heritage, one rooted in the legacy of an extraordinary investigator.

A formidable woman in investigations

Zena Scott Archer was not just respected; she was widely regarded as one of the most capable investigators of her time. She began her career at just 17, learning the trade from her father, who founded Scott’s Detective Bureau. From her very first assignments, she displayed intelligence, resourcefulness and determination, qualities that would define her entire career.

She worked on a wide variety of cases, from serving legal documents and tracing to complex corporate enquiries and international investigations. Her skill for observation and her ability to read people, situations and patterns, set her apart. She became known for her ingenuity and creativity, often using disguises to gather information that others could not.

In a profession historically dominated by men, Zena commanded significant respect and authority. At a time when communication and information access were far more limited than they are today, professional networks were essential. She developed strong international connections and earned the admiration of investigative professionals across Europe and beyond.

Her career spanned nearly five decades and encompassed specialties including corporate fraud, tracing missing assets and international investigative coordination. She also became a mentor to younger investigators, encouraging them to uphold ethical standards while embracing innovation.

Later, she broke new ground as the first woman to serve as President of the World Association of Detectives, a role that affirmed the respect she held among peers worldwide.

Zena combined professional excellence with personal warmth. She had time for people, and she always had time for the work. Those are not small qualities in a good investigator, and they mattered deeply to me.

She embodied what good investigation should look like: Thorough, professional and grounded in respect for others. That mindset has stayed with me throughout my career.

Zena’s contribution is recognised through the Zena Scott Archer Investigator of the Year Award, established by the Association of British Investigators. I was honoured to receive that award in 1995, a recognition that made her influence on my career very real and personal.

Why the name matters

My own career in private investigations began in 1990, when I joined Ellison and Gough’s litigation support and investigations team as a partner under Bert Ellison, a highly respected former police officer and mentor to me.

In 1998, I acquired Zena’s company, Scott’s Detective Bureau and the name was merged with our business before we eventually sold it.

When I later established a new firm, I initially named it Ellison Scott Archer – a deliberate recognition of the two people who helped me get started as an investigator.

That heritage informs who we are today.

Why Zena’s story matters

International Women’s Day is often about looking forward, but it is equally important to look back.

Long before conversations about representation became mainstream, women like Zena Scott Archer were building international networks, leading global organisations and setting professional standards in industries that were not necessarily designed with them in mind.

Her story reminds us that women have shaped investigative practice, leadership and international cooperation for decades.

Her name lives on in an award.
It lives on in the standards she helped embed in the profession.
And it lives on in our business.
