Frequently Asked Questions
Q: What is CNAPP and why does it matter?
CNAPP stands for Cloud Native Application Protection Platform. It unifies posture management and runtime protection to cover misconfigurations, vulnerabilities, and threats across your cloud environment.
Q: Do I need both EDR and DLP?
Yes. EDR (Endpoint Detection & Response) catches sophisticated endpoint threats, while DLP (Data Loss Prevention) prevents sensitive data exfiltration. Together, they form a layered defense.
Q: How much should I budget for cybersecurity?
Aim for 5–10% of your IT budget. With cloud tools, you shift from CapEx to predictable OpEx, making planning easier.
Q: Can I mix vendors?
Absolutely. Many small businesses run DNS filtering from one vendor, EDR from another, and backup from a third. Just ensure your tools integrate or export logs for centralized monitoring.
