Executive assistants sit close to the most sensitive parts of a business, and attackers know it. In 2026, phishing, business email compromise, and AI voice cloning all target the same weak point, trust.

An executive assistant security playbook gives people one clear way to verify requests, protect schedules, and handle confidential information. It also keeps small mistakes from turning into costly ones.

The best playbooks are simple, specific, and easy to use under pressure. Start with the risks your team faces most.

Start with the risks that hit the EA seat

Executive assistants now deal with more than spam and odd links. Attackers study calendar habits, vendor names, travel plans, and payment routines. Then they send a message that feels familiar enough to pass a quick glance.

AI makes that harder. A fake voice note can sound like a leader. A polished email can copy tone, urgency, and timing with scary accuracy. For a broader view of the threat shift, see AI-powered cyber attacks in 2026 and how executive assistants can strengthen cybersecurity.

Business email compromise often starts with a simple request. A bank detail changes. A gift card request appears. A wire needs to go out before a meeting. If you want a deeper primer, review TechTarget’s BEC prevention guide.

Travel security matters too. Shared itineraries can reveal where an executive will be, when they are away, and who can reach them. That information helps an attacker plan the next move.

Build the rules and SOPs

A good playbook turns judgment calls into plain steps. It should work for a two-person admin team and for a large enterprise desk.

Use a simple table so everyone knows what to do.

Situation	Required action	Owner
Urgent payment request	Verify through a known phone number and finance channel, never by replying to the email	EA and finance
Calendar or travel change from an executive	Confirm on a known secondary channel before updating systems	EA and executive
Password reset or MFA change	Open an IT ticket and record the request source	EA and IT
Confidential file share request	Check classification, limit access, and log the recipient	EA and manager

That kind of table keeps the playbook useful during a busy day. It also helps new assistants learn the rules fast.

A sample SOP line can read like this, “If a request involves money, access, travel, or confidential information, pause, verify through a known channel, log the action, and escalate anything unusual to IT or finance.” Short language works better than policy jargon.

The EA handles first review and logging. The executive sets approval limits. IT owns MFA, device checks, and incident response. Finance confirms payment changes. Office, travel, or security teams watch itinerary risk.

Train people before an incident

Training works when it feels close to real work. Show assistants how to handle a fake wire request, a spoofed calendar invite, and a voice call that sounds like a leader.

Quarterly drills help more than slide decks. Run a 15-minute exercise with the executive, finance, IT, and travel contact. Keep the scenarios real, because people remember what they practice.

Do use call-back numbers already saved in contacts. Do verify unusual requests through a second channel. Don’t rely on caller ID, and don’t forward sensitive files to personal accounts.

If a request changes money, identity, or timing, verify it on a known channel before you move.

Many teams also pair the playbook with simple tools, like password managers and phishing filters. These cybersecurity apps and tools for executive assistants are a useful starting point.

Keep a one-page quick reference near the desk and inside the team wiki. It should list approved phone numbers, escalation contacts, and the exact steps for payment changes, travel changes, and lost-device reports.

Review and update it on a schedule

A playbook gets weak when it sits untouched. Review it every month for contacts, phone numbers, travel vendors, and approval limits. Update it after org changes, new executives, new devices, or a real phishing attempt.

Keep a change log. Note what changed, who approved it, and when staff were briefed. That way, the playbook stays current instead of drifting into an old file.

Set one owner for review. Without an owner, updates wait until the next incident, and that is usually too late.

An executive assistant security playbook works best when it stays short, clear, and current. It should answer the same hard questions every time, so people can act without guessing.

That is what protects calendars, travel plans, inboxes, and confidential files. The strongest playbooks turn trust into a process, and that matters more than ever in 2026.
