Expertise & credentials

The credentials and expertise behind our work.

Certified leadership, deep framework fluency and engineers who have built what auditors test. Here is what stands behind every MarkTillson engagement.

Led by certified leadership

Lola Osoba, CISA, CISM

Our founder holds two of the most respected credentials in information systems assurance and security management, both issued by ISACA. They set the bar for how every MarkTillson engagement is scoped, delivered and reviewed.

CISMCertified Information Security Manager

The standard for leaders who govern security programs and manage risk. It is why our programs keep working after the engagement ends.

Every proposal names the practitioners who will lead your engagement, with their experience and individual certifications.

What to ask any adviser before you sign.

01Who does the fieldwork?

Ask for the names, certifications and experience of the people on site, not only the people in the pitch.

02Have they built it, or only reviewed it?

Advisers who have engineered controls give better advice about testing them.

03How do findings get ranked?

By scanner score, or by what would actually hurt the business?

04What is left behind?

Evidence, runbooks and trained owners, or just a report?

Independence. We tell you plainly when a task belongs with your certification body, CPA firm or accredited assessor, and we work alongside them so their assessment goes smoothly.
