Developer & Vendor Dependency Risk
The “bus factor” is the number of team members that need to be hit by a bus (or quit) before your project is in serious trouble. For many businesses, that number is one.
If your solo developer quit tomorrow, your dev shop went out of business, or your agency relationship ended badly—could your business survive?
Most founders don’t know they have critical dependencies until it’s too late.
Why This Matters (Solo Developers, Agencies & Dev Shops)
Solo Developer Risks:
- 70% of businesses experience critical disruption when they lose access to their solo developer, dev shop, or agency
- Knowledge transfer takes 3-6 months on average with no guarantees of success
- 89% of former employees still have access to company systems after departure
Agency & Dev Shop Risks (Often WORSE):
- 30% of all data breaches now involve third parties—double the 2024 rate (Verizon DBIR 2025)
- 36% of breaches originated from third-party compromises (IBM 2025)
- $4.91 million average cost for supply chain breaches—the 2nd costliest attack vector (IBM 2025)
- 45% of organizations experienced third-party business interruptions in the past two years (Gartner 2023)
- Code ownership defaults to the creator - if not in your contract, they own YOUR code
- Many businesses discover their infrastructure is hosted in the agency’s AWS/Azure account - they don’t own it
- Domain registered under agency account = you lose your web presence if relationship sours (vendor lock-in)
Bottom Line:
- Average cost of unplanned vendor departure: €25,000-€75,000 in lost productivity and emergency hiring
- Most founders discover gaps only when something breaks - usually at the worst possible time
What Actually Happens: Real-World Cases
These aren’t hypothetical risks. Here’s what happens when vendor dependency goes wrong:
The AWS Account Lockout
An IT professional left a company with root AWS account access. The MFA was tied to his corporate phone, which the company deactivated. When their SQL server became unresponsive, they discovered they were completely locked out—no way to access their own infrastructure. (AWS account recovery guidance)
Domain Ransom Demands
Multiple documented cases of developers and agencies demanding $5,000+ to transfer domains back to clients who paid for them. The pattern: agencies register domains in their name “for convenience,” then refuse to transfer when relationships end. In one case, an agency changed the client’s site to “under construction” and demanded ransom to restore it. (Domain hostage situations)
The Disappeared Developer
A developer named “John” stopped responding to emails and calls—for months. Multiple clients had projects on his development server, and no one had access. The company investigated whether he was still alive and eventually worked with the hosting provider to recover access, but the emergency scramble cost time, money, and client relationships. (Software developer disappeared)
Why Share These?
Not to scare you—to show you what’s preventable. Developers get sick, have family emergencies, win the lottery, or yes, get hit by buses. Agencies go out of business or relationships end badly. These aren’t hypothetical scenarios—they’re common enough that AWS has recovery procedures specifically for this situation. This assessment helps you identify and fix these gaps before they become emergencies.
What This Assessment Reveals
This 10-question assessment identifies critical vulnerabilities across your infrastructure:
- Documentation gaps - Can someone else understand your systems?
- Access control - Do you own your infrastructure or does your developer/agency?
- Code repository ownership - Can you access your source code?
- Domain & DNS control - Do you control your web presence?
- Backup readiness - Can you actually restore from backups?
- Knowledge distribution - Is everything in one person’s or one company’s head?
- Deployment autonomy - Can you ship updates without your developer/agency?
- Monitoring & alerting - Will you know when things break?
- Disaster recovery - Can you survive a catastrophe? (Test your DR plan)
- Infrastructure audits - Are you staying current?
