The Confidential Search: Five Places a Search Leaks, and Why Retained Closes Them

Some searches can't be announced. You may be replacing an executive who doesn't know yet, or quietly lining up a successor for a founder who plans to step back next year. Sometimes just posting the role would tell competitors where you're going. In those searches, confidentiality isn't a feature of the service. It is most of the job, and the way you pay the search firm decides whether it can be done at all.

Why a leak costs more than the fee

When a search leaks, the first casualty is usually the team, not the candidate list. Visier's research on what it calls turnover contagion, reported by HR Dive in 2022, found that after one person resigns voluntarily, their teammates become 9.1% more likely to leave. That risk starts about 45 days after the first departure and peaks around day 70. A rumor that the boss is being replaced does much the same thing before anyone has actually left.

And the team is already restless. In Robert Half's April 2026 survey of more than 2,000 US workers, 46% planned to look for a new job in the next six months, up from 27% a year earlier. A leaked leadership search gives the people who were half-looking a reason to finish.

The incumbent is the second casualty. An executive who learns of the search early either leaves on their own timetable, usually mid-quarter, or stays and stops investing in the role. Both are expensive, and neither is the transition you planned. Then come the candidates. The people worth hiring for a senior seat are employed, and the risk they carry in talking to you is being exposed to their current employer. They take that call only from a firm they trust to protect them.

Five places a search leaks

Confidential searches rarely fail through one dramatic breach. They leak through ordinary steps that nobody designed for secrecy.

1. The job posting. A public posting for a VP of Finance at a company that already has a VP of Finance announces the search to everyone, including the VP. A confidential search runs without a public posting, usually under a codename, with a blind specification that describes the company by sector, size and region rather than by name.
2. The résumé race. When several contingency firms work the same role, each is paid only if its own candidate is hired. That rewards speed, so each firm calls as many people as it can, and every call tells one more person that the seat is open. Three firms on one role means three call lists and three sets of people who now know.
3. The first call. In a confidential search, the first conversation describes the opportunity, not the company. The name comes out only after the candidate is interested and has agreed to keep it private. A recruiter who leads with the company name to get a callback has already spent the confidentiality.
4. The backchannel. Informal reference calls are where many searches quietly leak, because the person you call often knows your incumbent or the candidate's boss. The rule that holds: no backchannel without the candidate's consent and the client's sign-off on exactly who gets called. We covered why careful verification matters in The Verification Ladder.
5. The inside circle. Plenty of leaks start at the client. A calendar invite titled "CFO interview," an assistant booking rooms, a board member mentioning it at dinner. A confidential search keeps interviews off-site or on neutral calendar names, and keeps a short written list of the insiders who know.

Every additional firm working a role is one more list of people who know the seat is open.

The industry's own standards describe the model these five controls depend on. The AESC, the executive search profession's global association, says in its Professional Practice Standards that members keep sensitive client and candidate information "on a strictly need-to-know basis," and that member firms "operate on a retained and exclusive basis for executive search."

Why the fee structure decides whether confidentiality is possible

Heidrick & Struggles describes the difference plainly in its 2024 annual report to the SEC. Retained search firms "generally are compensated for their services regardless of whether the client employs a candidate identified by the search firm and are generally retained on an exclusive basis." Contingency firms, in contrast, "are compensated only upon successfully placing a recommended candidate."

Read that with the five leak points in mind. A firm paid only when its candidate wins has every reason to move fast and wide, which is exactly what exposes a confidential search. A single firm paid to run the process has no race to win, so it can afford the slow, controlled version: one script, one call list, one record of who knows. Confidentiality comes from exclusivity, and exclusivity comes from the fee structure. We set out the broader cost and incentive comparison in Retained vs. Contingency Search.

How a retained search is actually paid

This is the part most firms are vague about, so here it is in the open. The large public search firms disclose their terms in SEC filings. Heidrick & Struggles says its retainer is typically "approximately one-third of the estimated first year compensation for the position to be filled," plus indirect expenses charged as a percentage of the retainer, and that it generally bills "in one-third increments over a three-month period commencing in the month of a client's acceptance of the contract." Korn Ferry's 2026 annual report describes its search fees as "generally one-third of the estimated first-year cash compensation of the placed candidate, plus a percentage of the fee to cover indirect engagement-related expenses." If the final package comes in higher than estimated, both firms bill an extra amount on the difference.

On a role with $240,000 in first-year cash compensation, one-third is $80,000 before expenses. Billed the large-firm way, that is roughly $26,700 a month for three months, on the calendar, whether or not a finalist is on the table yet.

We bill against progress instead of the calendar. An ETHOSLINK retained search is typically paid in parts: one at engagement, sometimes one at a midpoint milestone such as the presentation of the slate, and the balance when the hire is made. Each payment corresponds to work you can see.

• At engagement: the brief, the success profile for month 24, the codename and blind specification, and a confidential map of the market.
• At the midpoint: a slate of up to three personally vetted candidates, each interviewed in depth and referenced only with their consent.
• At the hire: offer and resignation management, including the counteroffer most strong candidates will get (see The Counteroffer Trap), then a 30/60/90-day integration cadence. Every placement is guaranteed, and if the role changes mid-search we run it again at no charge.

Terms are set per search and written down before work starts, which is also what the AESC standards ask of every member firm.

When contingency is still the right call

None of this makes contingency wrong. For a mid-level role with a deep pool of active candidates and nothing to hide, paying only on placement is sensible, and we run contingency searches too. The line is the seat itself. If announcing it would cost you a team member, a customer, a competitive edge or an incumbent's last good quarter, the search needs one exclusive partner, and that means retained.

It also doesn't have to leave the seat empty while the search runs. If the incumbent is leaving or has already gone, a fractional executive can hold the role while the confidential search proceeds. That is the bridge we described for finance in Your CFO Just Gave Notice, and it works the same way for operations, revenue and technology seats through our Fractional C-Suite.

The searches that stay quiet aren't kept quiet by good intentions. They stay quiet because one firm owns the process, controls every point where it could leak, and is paid in a way that rewards doing it carefully. If a seat is coming open that you can't announce, that is the search to start with. More on how we run them is on our Executive Search page.
