Security posture for a sensitive operations manual

Any system that holds continuity data must assume motivated attackers and sleepy users. Defense in depth-session hygiene, cron authentication, environment validation-reduces whole classes of incidents.

Ask vendors how they think about least privilege

Role isolation between CFO and owner experiences is a signal: the product was designed for real firms, not a single-role hobby app.

Your manual is only as safe as your habits

Pair Stillago with good device security, MFA on email, and periodic reviews with counsel for anything legally sensitive.

Sensitive data deserves defense in depth

A continuity manual is a high-value target because it concentrates operational truth. Security is not a single feature; it is a posture: session hygiene, rate limits, strict environment validation in production, and careful logout behavior. Ask vendors how they think about abuse cases, not only happy paths.

Role isolation between advisor and owner experiences is a signal that the product was designed for real firms. It reduces the chance that a CFO workflow accidentally becomes a backdoor into private owner narrative.

Pair product security with household hygiene

• Protect email like it is the master key-because it often is.
• Prefer hardware keys or app-based MFA where possible; document recovery paths.
• Review what you store: fewer secrets in text fields reduces blast radius.

Read CFO visibility boundaries, devices and trusted contacts, and the MFA cliff as a practical trilogy.

Assume breach scenarios and reduce blast radius

Ask what happens if a laptop is stolen, if email is compromised, or if a family member accidentally shares a link. Reduce blast radius by storing fewer secrets in plaintext and by using scoped access paths.

Rotate emergency artifacts when personnel changes. Old links and old phone numbers are a common failure mode.

Keep audit trails where they help, not where they harm

Transparency features should protect users without turning the product into surveillance theater. The goal is safety with dignity.
