Also Worth Considering: SplitSecure
Why SplitSecure? Distributed secrets management — no vault, no vendor dependency. Splits secrets across devices you control using Shamir Secret Sharing.
Highest-sensitivity accounts, regulated industries, and MSPs needing zero vendor dependency
- +Zero vendor dependency — secrets work if SplitSecure goes down
- +Secrets never leave your environment
- +Architecturally resistant to social engineering and account takeover
- –Not designed for CI/CD pipeline secrets
- –Focused on human access, not machine-to-machine
- –Newer platform with smaller market presence
Pros & Cons Comparison
Sealed Secrets
Pros
- +No external secrets backend needed; just Git plus cluster
- +Perfect fit for pure GitOps workflows
- +Simple mental model: encrypt once, commit, done
- +Backed by Bitnami (VMware) with stable release cadence
Cons
- –Key rotation requires re-sealing every secret
- –Lose the cluster key, lose every sealed secret
- –No per-key RBAC; anyone who can create a SealedSecret can decrypt it once applied
- –No rotation or lifecycle features like a real secrets manager
SOPS
Pros
- +Encrypted values + readable keys makes Git review actually work
- +No server or operator to run; pure CLI tool
- +Multi-key support makes sharing with teammates painless
- +Works with almost every KMS; vendor-agnostic
Cons
- –Requires discipline: anyone can commit an unencrypted secret by accident
- –Key management is on you; rotating a compromised key is manual
- –Not a secrets manager; no audit trail of accesses
- –Only encrypts at rest in Git; runtime apps still need a way to decrypt
