Conclusion

When you’re choosing between data management services provided by various companies, ask each vendor to walk you through a data breach they actually had and how they fixed it. Vague answers are a red flag, while specific, slightly embarrassing details mean real experience. Also, don't skip the boring stuff and ask who owns your data schemas after the contract ends. That question alone has saved companies from painful vendor lock‑in.
