Secrets here today, disappear tomorrow
Few industries require the level of privacy and security as banking. And few banks have as extensive security demands as ABN AMRO.
The bank provides a comprehensive line of products and services for its customers. But securing the systems, applications, and data that enable those services is a daunting task for the company's 400-person Corporate Information Security Office (CISO).
"Executing the access and identity governance across our various customer and backend business applications has been challenging but manageable with our existing security solutions, even as we've added thousands of new accounts and users," says Ton van Dijk, the bank's agile product owner in the identity and access space. "However, our legacy system required an additional module and hands-on monitoring to manage the ephemeral backend secrets and keys among our internal apps and infrastructure, so we decided to look for a more seamless, automated way to address such a critical element of our business."
Preventing a domino effect
Though the financial services industry has a reputation for requiring proven technologies that often makes early technology adoption challenging, ABN AMRO embraced a digital transformation to modernize and future-proof its business. Yet, while the multi-cloud IT strategy and containerized development environment provided a much-needed efficiency boost for its growing product portfolio, it also created a new set of complexities and challenges for the CISO team.
"Secrets management is a business-critical element of our work because if any of the secrets are compromised, they'll have a huge downstream effect," Van Dijk says. "Even a single compromised signing certificate can take an entire system offline, which means possibly losing access to online apps or exposing them to the risk of someone maliciously injecting something into the apps. There's really no room for error."
The bank's previous secrets management solution featured a number of out-of-the-box systems connectors that still required a good amount of programming to set up a new application. Worse, the self-managed platform didn't integrate well with the team's Kubernetes instance, which meant one of the team's engineers had to create a custom connector for new applications or containers that could take several days to reach a test-ready stage.
Additionally, ABN AMRO knew that they needed to prevent secrets sprawl. As many applications and platforms come with their own secrets engines, having that central oversight is critical to be able to quickly revoke secrets in case a serious compromise would happen. When secrets are spread across a multitude of solutions, that is going to be difficult to control.
"The whole process revealed to us that having an on-premise, self-managed secrets system that required third-party support for any type of change was a time-consuming and inefficient way to manage a crucial piece of our operations," Van Dijk explains. More broadly, "it became clearer by the minute that we needed a cloud-native environment that supported containerized development and emphasized automation — without having to undertake a complete and expensive replatforming or technology refresh."
Securely managing ephemeral secrets
Reducing reliance on manual secrets management processes
Onboarding consumer and internal applications to a secrets server
Data and systems security underpins every aspect of our operation. With Vault we have the agility, transparency, and world-class support to confidently build out solutions for today’s and tomorrow's needs without having to constantly worry about one mismanaged secret wreaking havoc on all our hard work.

Central, dynamic secrets management for a booming business
Eager to improve its secrets management practices by eliminating hardcoded credentials from internally developed applications and scripts, the ABN AMRO CISO team adopted HashiCorp Vault after running a proof of concept involving the team's software development and security specialists.
With Vault, the CISO team has implemented a central secrets management repository and eliminates human operators having to manually apply secrets policies to new applications and hosts. The cloud-agnostic platform dramatically simplifies shared credentials and secrets management by automating many of the most time-consuming and laborious processes.
"Vault's dynamic secrets and API encryption capabilities, coupled with its secrets injector and secure communications, make it possible to confidently onboard apps to our container platform with a fraction of the time and effort as before," Van Dijk says. "We're now able to manage ephemeral secrets in AWS and Azure in ways we couldn't before without adding headcount, cost, or unnecessarily long learning curves."
A transformative technology experience
According to Van Dijk, Vault has been a revelation for his organization by supporting continuous integration and deployment that the previous solution couldn't, and freeing his time to work on higher-value initiatives, like potentially coordinating migration of SSL certificates from other internal platforms or planning a future encryption-as-a-service offering.
While most organizations tend to measure success only by straight return on investment (ROI) metrics — seemingly appropriate for a financial services institution — Van Dijk and his team are instead focused on Vault's business enablement capabilities to evaluate its impact.
"Even though we aren't yet primarily focused on measuring things like the number of certificates injected into consumer apps, we will be onboarding as many as 25 new platforms in the coming months, which is a significant part of our overall growth plan," he says. "None of that is possible without a secrets management solution like Vault to run Kubernetes for our most critical workloads and to automatically onboard new platforms with specific policies and configurations right out of the gate."
Crediting HashiCorp's responsive support team, extensive resource library, and integrated products like HashiCorp Consul for his team's rapid deployment of Vault, Van Dijk is optimistic about his team's ability to execute larger corporate initiatives in the future.
"Centralizing our ephemeral secrets management into Vault cleared the biggest hurdle to creating the digital capabilities that internal teams and our customers have come to expect in this day and age," he says. "Data and systems security underpins every aspect of our operation. With Vault we have the agility, transparency, and world-class support to confidently build out solutions for today's and tomorrow's needs without having to constantly worry about one mismanaged secret wreaking havoc on all our hard work."
Eliminated costly ephemeral secrets modules to reduce cost and complexity
Dynamic secrets enabled onboarding of two dozen new platforms
Established a foundation for an encryption-as-a-service model
ABN AMRO is using HashiCorp Vault to create a centralized secrets management system spanning its AWS, Azure, and other internal applications that automates secrets injection and API encryption for greater efficiency and fewer critical secrets errors.
