Should a B2B software company sell direct or through channel partners?
The evidence
The disclosed channel shares.
Netskope 94.8% indirect in H1 FY26. Tenable 94%. Zscaler 84% — $2.07B of total, first nine months FY2026. Fortinet, SentinelOne and Varonis each state in their own filings that substantially all sales are fulfilled through channel partners.
Security is moving opposite to the rest of IT.
Channel share of all global IT spend is falling — 69% in 2025, 65% in 2026, 63% forecast for 2027. Security is rising against that trend, from the same research house.
Every documented vendor move went one way.
Across 2025–26 we found no vendor moving toward direct. CrowdStrike's MSSP business grew from under $100M to more than $1.3B in just over three years. Proofpoint, SonicWall, Sophos, ThreatDown and Rapid7 all restructured toward partners.
The concentration that creates is understated.
SentinelOne discloses two channel partners at 18% and 12% of revenue — 30% through two counterparties on a business above $1B. Their accounts-receivable shares are 21% and 14%. Fortinet discloses a single distributor at 32% of total net accounts receivable. The cash exposure is larger than the revenue exposure, and only the revenue number tends to get discussed.
No margin figure appears here, and that is deliberate.
No deal-registration discount rate, distributor discount, or direct-versus-channel gross-margin comparison is publicly sourceable for any security vendor. Partner programme guides say “margin uplift” without numbers. Any margin figure in this answer would be a guess, so there is none.
What would have to be true for this to be wrong
