There is a particular kind of trust that a bank cannot buy or borrow,the quiet confidence customers place in the belief that their money, their data, and their digital lives are safe behind the institution’s walls.

For nearly twenty years, Diana Agaba Tukundane has worked to earn exactly that kind of trust, and this week, Stanbic Bank Uganda made it official: she is the bank’s new Chief Information Security Officer, and in a move that carries weight well beyond the title itself, a newly confirmed member of the bank’s Executive Committee.

The appointment is less a debut than a homecoming of sorts. Tukundane has spent years inside Stanbic’s information security function, most recently as Head of Information Security, where she built a reputation as one of the sharpest cybersecurity minds in Uganda’s financial sector. Colleagues and industry peers alike know her as a fixture at forums like the Africa Cyber Defense Forum and East Africa’s premier information security conferences, where she has spoken candidly about resilience, governance, and the particular burden and opportunity of being a woman leading in a field still overwhelmingly defined by men.

But it is her seat at the executive table that marks the real inflection point here. In its announcement, Stanbic described her as a respected cybersecurity leader whose work over nearly two decades has been pivotal in strengthening the bank’s cyber resilience and safeguarding customer trust,and confirmed that her new role now places her formally among the small circle of executives shaping the bank’s overall direction. That distinction matters.

Cybersecurity is no longer a back office function bolted onto IT; it is a board level concern, woven into strategy, reputation, and the bank’s fundamental promise to its customers.

By confirming Tukundane on EXCOM, Stanbic is saying, in the clearest terms available to a corporation, that the conversation about digital trust now happens where the big decisions are made, not after them.

Her rise has coincided with a period in which African banking has been forced to reckon, often in real time, with threats that evolve faster than regulation can keep pace ,from phishing schemes targeting mobile money users to increasingly sophisticated attempts to breach enterprise networks. That she has spent this period not merely reacting to risk but architecting the frameworks to anticipate it says something about the seriousness with which she approaches the work, and about why the bank saw fit to hand her a permanent voice in how it is run.

For Tukundane personally, the appointment caps a career built as much on mentorship as on technical mastery. As a vocal advocate for women in STEM and a familiar voice on panels encouraging young women into cybersecurity and technology careers, she has made a habit of pulling others up even as she has climbed. It is likely no accident that Stanbic’s tribute to her arrives dressed in language about resilience and forward-looking leadership qualities she has spent years modeling, publicly, for a generation of women watching to see what is possible in the field.

Congratulations continue to pour in for Tukundane, whose confirmation to EXCOM places her among a small but growing number of women occupying the executive suite in East Africa’s banking and technology landscape.
