The Business of Cyber Security

The Graduating Class Tracker

In March 2026, XBOW raised a $120M Series C at a $1B+ valuation (DFJ Growth and Northzone leading; ~$237M raised in total since 2024) — a marker of a company entering the graduating class: well-funded and scaling, but not yet at the scale or profitability that supports an independent IPO. Every venture-backed cyber company that survives its category-creation phase eventually arrives at the same fork that 07e describes: grow into a public company, get acquired, recap with a sponsor, or get bundled away. The graduating class is the population sitting at that fork, and it is a primary sell-side origination list.

What "the graduating class" means

A graduating-class company is one that has proven product-market fit and reached real scale but is too small to IPO comfortably and too valuable to ignore as an acquisition target. Concretely, the cohort clusters around these traits:

This cohort exists structurally, not by accident. The IPO window is an episodic regime (see 29b) — open in 2021, mostly shut 2022–2024, selectively open again with SailPoint's re-IPO (priced Feb 12 2025), Netskope (Sep 17 2025), and Rubrik (Apr 2024). Most scale-ups cannot time their readiness to the window, so the strategic sale is the base-rate exit, not the exception.

The graduation funnel

The graduating class: ARR vs. time since last round Est. ARR (x) vs. time since last major round (y) — the sell-side window is the shaded band 4 yr+ 2 yr <1 yr time since last major round ~$30M ~$75M ~$150M $200M+ estimated ARR → SELL-SIDE WINDOW scaled, growth cooling IPO-track (rare) Orca Aqua Cybereason Vectra AI Sysdig Semperis Chainguard (just raised) XBOW (just raised) Cato Snyk Abnormal Illustrative positioning from public reporting; ARR figures are estimates (see table). Exhibit: The Business of Cyber Security.
Gold dots sit in the sell-side window — scaled, >2 years past their last big round, growth cooling. Grey dots are recently re-funded (the clock just reset). Blue dots have the scale/growth to keep the IPO option open. Positions are illustrative; the live source of truth is the Cyber Ecosystem Graph.

The funnel runs seed → Series A/B (build the product) → Series C/D (scale the GTM) → the fork. Four outcomes:

  1. IPO — needs ~$200M+ ARR, durable 30%+ growth, and an open window. The rarest path; most "IPO-track" companies actually exit via #2.
  2. Strategic sale to a platform — the base case. A PANW/CRWD/Cisco/Zscaler/Microsoft (see 03m) or an adjacent strategic buys the category capability and the customer base. This is the classic sell-side mandate.
  3. Sponsor recap / PE platform — a Thoma Bravo / Vista / growth-equity sponsor (see 06) takes a majority stake to run a value-creation playbook, often as a roll-up nucleus.
  4. Down-round, acqui-hire, or wind-down — the distressed branch for companies that stalled with burn intact and no buyer urgency.

The watchlist: graduating-class candidates by sub-segment

The table maps a representative set of venture-backed cyber scale-ups to their likely fork. All ARR figures are estimates triangulated from public reporting and labeled accordingly; the Cyber Ecosystem Graph holds the live, enriched values. Inclusion is not a claim that a process is underway — it is a structural read of where each company sits.

Company Sub-segment Est. ARR (rough) Last major round (public) Likely fork
Cato Networks SASE ~$300M+, ~43% YoY (CNBC, Feb 2026) Series G @ ~$4.8B (2025) IPO-track or premium strategic
Snyk AppSec / developer ~$300M+ (est.) Late-stage / secondary IPO-track; developer-moat
Abnormal AI Email / AI security ~$200M+ (est.) @ ~$5.1B (2024) IPO-track or strategic (bundle pressure, 03j)
Orca Security CNAPP / cloud ~$75–150M (est.) Series C/D (2021–22) Sell-side window — Wiz/Palo Alto comps
Aqua Security Cloud / container ~$100M+ (est.) Series E (2021) Sell-side window
Sysdig Cloud / runtime ~$100M+ (est.) Series G (2022) Sell-side window or recap
Cybereason Endpoint / XDR ~$100M (est.) Recapitalized (SoftBank-led) Sell-side / consolidation
Vectra AI NDR / SecOps ~$100M+ (est.) Series F/H (2021–23) Sell-side window
Semperis Identity / AD resilience ~$100M (est.) Series C @ ~$1.6B (2022) Sell-side window — identity pull (03a)
Island Enterprise browser scaling fast (est.) Series E @ ~$4.8B (2025) IPO-track or premium strategic
Chainguard Software supply chain early-scale Series D @ ~$3.5B (2025) Re-funded — clock reset
XBOW Autonomous offense / pentest early-scale Series C @ $1B+ (Mar 2026) Re-funded — clock reset (see 20a)
ThreatLocker Endpoint / Zero Trust (app control) scaling (est.) Series F, $190M @ ~$1.6B+ (Jul 2026) Re-funded — clock reset (see 07)
Veza Identity / access governance early-scale Series D (est.) Watch; identity consolidation
Huntress SMB MDR >$250M, +65% YoY (Jul 2026, company-stated) Series D @ ~$1.5B (2024) Re-funded pending — raise signalled for early 2027

→ The companies sitting in the sell-side window (gold dots above) share a profile: a 2021–2022 mega-round, a cloud or identity or SecOps category now mid-consolidation, growth that has cooled from triple digits toward the 30–40% band, and no obvious next financing. That is precisely the 07f "efficient-but-slowing" quadrant — worth more sold to the right strategic than re-financed.

Huntress is the counter-case, and it is worth stating plainly because it moved off this list. In July 2026 the company disclosed that it had passed $250M in ARR, growing 65% year over year, protecting more than 270,000 businesses, 14 million identities and 5.5 million endpoints across more than 100 countries, at 130% net revenue retention (Huntress, Jul 30 2026). Its CEO has said the company is planning a round in early 2027 that could triple the ~$1.5B mark set in 2024 — implying roughly $4.5B — and that pre-emptive rounds valuing the company at upwards of $5B have been declined since 2024 (Axios Pro, Jul 30 2026). Two things follow for the watchlist logic. First, the exit-readiness signals below are conditional on decelerating growth: a company compounding at 65% at $250M scale fails the trigger, and the correct classification is "re-funded, clock reset," not "sell-side window." Second, the profile that produced it — SMB and mid-market, MSP-channel-led, per-seat pricing, a market that venture investors dismissed as non-venture-scale for most of a decade — is the segment where scale accrued fastest in this cycle, and it is under-represented in the mega-round cohort above. See MDR and Distribution & Marketplaces.

Exit-readiness signals

A watchlist is only useful if it is triggered. The confirming signals, in rough order of strength:

  1. Growth crosses below ~35% with efficiency intact — the 07f trigger; the financing math gets harder and the strategic math gets better at the same moment.
  2. 24–36 months elapsed since the last big round with no new raise announced — the board's return clock is running.
  3. A platform acquirer makes a tuck-in in the same sub-segment — validates the category and signals the consolidation phase has begun (e.g., the AI-security sweep, 03l).
  4. An exec move that reads as exit-prep — a new CFO with IPO/sale experience, or a banker added to the board.
  5. The category's "fork" arrives (07e) — a bundler announces a competing native feature, compressing the standalone window.

The bear case

The graduating-class thesis can be wrong in three ways. First, re-absorption: many of these categories get bundled into platforms as features before a clean exit, leaving the standalone company stranded (the 03l/03j risk). Second, the window reopens: if the IPO regime swings open, several "sell-side" names re-route to public markets and the strategic discount disappears. Third, the AI reset: AI-native entrants can leapfrog a scaled incumbent's category, turning a "graduating" company into a melting asset rather than a premium target. The watchlist must therefore be re-scored continuously, not set once.
