A good executive vulnerability brief fits on one page and answers six questions: what happened, are we running it, are we exposed, is it being exploited, what are we doing, and when is the next update. Everything else goes in an appendix that nobody has to read.
Why one page
Executives decide on three things: whether to interrupt other work, whether to tell customers, and whether to spend money. A page that answers those lets them decide in minutes. A deck with twenty slides makes them hunt for the answer, and they will ask the one question the deck buried.
The template
| Field | Content | Length |
|---|---|---|
| 1. What it is | Name of the flaw and what an attacker could do, in one plain sentence | 1 sentence |
| 2. Are we running it | Yes, no, or still checking, with the date and time of the check | 1 line |
| 3. Are we exposed | Which systems, internet-facing or not | 2 lines |
| 4. Is it being exploited | Yes, no, or unknown, and the source | 1 line |
| 5. What we are doing | Actions taken, actions planned, owner | 3 bullets |
| 6. Next update | A specific time | 1 line |
Add one optional line at the bottom: a decision requested, if any. For example, approve an out-of-hours deployment, or approve a customer notice.
A worked example, with invented details
What it is: A flaw in a web framework lets an unauthenticated visitor run commands on the server. Are we running it: Yes, in two services, confirmed at 10:15 today by dependency inventory. Are we exposed: One service is internet-facing. The other is internal. Is it being exploited: Unknown. We checked the public exploited-vulnerability catalog and it was not listed as of 10:30. What we are doing: Upgrading the internet-facing service today (owner: platform lead). Adding a temporary filter at the edge meanwhile. Internal service scheduled this week. Next update: 16:00 today. Decision requested: Approve an evening deploy window.
That is under 150 words and covers everything an executive needs.
Where the facts come from
- Exploitation: CISA's Known Exploited Vulnerabilities catalog lists vulnerabilities known to be exploited in the wild and says organizations should use it as an input to prioritization (CISA). Absence from the list is not proof of safety, so say "not listed as of" and give the time.
- Severity: if you quote a CVSS score, quote its source. FIRST says it measures severity and should not be used alone to assess risk (FIRST).
- Inventory: a current list of components answers "are we running it" quickly.
What to leave off
Leave off the exploit mechanism, the full list of affected versions, the history of the library, and any speculation about who might be attacking. Put those in a linked technical note for engineers.
Leave off colour-coded risk ratings you cannot defend. If you use a rating, define it in one line.
Keep the format stable
Use the same page every time, so executives learn where to look. Number the versions and keep old ones. Over a few events the page becomes the shared language between security and leadership.
Try it yourself
Click through it at your own pace, or open it full screen. Look at how a new issue appears and gets a status. Each row maps to a field on the page: what it is, whether you run it, and what state it is in.
Where Safeguard fits
Safeguard offers dependency scanning, SBOMs and reachability analysis, which supply the inventory and exposure lines. The free scan at gold.safeguard.sh/scan is a starting point.
Quick check
Should the brief include a risk score?
Include a severity score with its source if people expect one, but lead with exposure and exploitation, which say more about your situation.
How often should it be updated?
At the time promised in the last version, and whenever a field changes.
