What Is BYOA? And Why It’s a Growing Security Concern

Most security professionals are familiar with BYOD—Bring Your Own Device. But BYOA, or Bring Your Own Application, is the newer and arguably more disruptive trend reshaping how organizations manage risk.
Employees now bring their own SaaS tools into the workplace—often without asking IT. They’re not trying to be sneaky. They’re just trying to get their jobs done more efficiently. But this well-intentioned behavior introduces major blind spots into your SaaS security strategy.
In this post, we’ll break down what BYOA is, why it’s happening, and how security teams can handle it without slowing down productivity. And if you’re wondering how to get visibility into all of it—yes, tools like Waldo Security can help, but we’ll get to that later.
What Is BYOA?
BYOA refers to employees using their own chosen applications—whether cloud services, SaaS tools, or productivity platforms—in a work context, usually without formal approval from IT.
Examples include:
Personal Google Drive or Dropbox accounts
Trello boards and Notion pages created outside the company workspace
AI tools like ChatGPT used for content or code generation
Slack, Zoom, Calendly, or other apps created with unmanaged credentials
While these tools might be convenient, they often exist outside of the organization's visibility and control.
Why BYOA Is a Problem for Security and Compliance
Employees often adopt these tools because the approved ones are clunky or outdated. But even one unmanaged SaaS connection can create real risk:
1. Data Security Gaps
Unvetted tools may not follow your organization’s security standards. Data might be stored in insecure environments or accessed by unauthorized parties.
2. Compliance Violations
For regulated industries (think HIPAA, SOC 2, GDPR), data handling requirements are strict. If sensitive information ends up in an unsanctioned app, your organization could face serious penalties.
3. Shadow IT Blind Spots
You can’t manage what you can’t see. Shadow IT—including BYOA—makes it harder for security teams to monitor access, detect threats, or investigate incidents.

4. Integration and Workflow Chaos
BYOA apps often don’t integrate well with core enterprise systems, causing siloed data, duplicated work, and fragmented collaboration.
Why Employees Love BYOA (And Why It’s Not Their Fault)
It’s worth saying: BYOA isn’t happening because employees want to undermine IT.
It’s happening because employees want to work efficiently—and when the tools they need aren’t provided, they’ll find their own.
Security teams must recognize this not as rebellion, but as a usability failure. If the official solution isn’t easy to use, people will sidestep it. The answer isn’t to ban everything. It’s to meet users where they are—and bring them back into the fold securely.
How to Manage BYOA Without Slowing Down Teams
Organizations that handle BYOA well do the following:
1. Discover What’s in Use
You can’t fix what you can’t see. Tools like Waldo Security use email and OAuth behavior to automatically discover connected apps across your workforce—including ones your IdP or CASB might miss.
2. Offer Secure Alternatives
If employees are flocking to better tools, take the hint. Work with them to approve and secure the tools they actually want to use. If needed, replace legacy apps with ones that balance usability and security.
3. Build and Share a SaaS Policy
Give employees clarity. Define:
Which tools are approved
How to request new apps
What the security risks are
Internal education is key to getting buy-in.
4. Embrace Zero Trust Principles
Assume every app and identity is a potential risk. Use:
Single Sign-On (SSO)
Multi-Factor Authentication (MFA)
Least privilege access controls
This won’t stop BYOA, but it limits its blast radius.
5. Shift Security’s Role from Gatekeeper to Partner
BYOA is ultimately a culture problem. The fix is collaboration, not control. Security teams that enable workflows—not block them—tend to earn long-term influence.
The Bottom Line
BYOA isn’t going away. Employees will continue using their preferred SaaS tools—whether you approve them or not.
Your goal isn’t to ban BYOA. It’s to manage it. That starts with visibility.
