Modern InsurTech carrier with publicly documented sublimit structure — the right pick when 'I want the sublimit table written in plain English so I can compare apples to apples against other quotes' dominates. Coalition publishes specimen policy language with relatively clear sublimit structure: ransomware typically 50% of policy limit (some broker portals show 100% available as endorsement upgrade), social-engineering endorsement standard at $250K-$1M depending on policy size, cyber-physical endorsement available for IoT/OT-exposed buyers (manufacturing + healthcare + utilities + transportation). War / nation-state exclusion uses the 2024 Lloyd's market wording (LMA5564 family) which explicitly excludes attacks attributed to nation-state actors as cyber-conflict — the operator-honest tradeoff is post-NotPetya/Merck the carrier is structurally MORE likely to deny on attribution-disputed claims than under pre-2022 wording. Reputation / brand recovery NOT covered (consistent with category). Pre-existing breach exclusion standard 'knew or should have known' wording.
Lloyd's syndicate that negotiates sublimits up to 100% of policy limit on enterprise placements — the right pick when 'I want the deepest sublimit headroom + the deepest IR roster when I actually file the claim' dominates. Beazley's enterprise placements often negotiate ransomware sublimits up to 100% of policy limit (vs the 25-50% category default) and social-engineering endorsements up to $1M-$5M for material BEC exposure. The Beazley Breach Response IR roster (Mandiant + CrowdStrike Services + Unit 42 + Coveware) is reportedly the deepest in the category — when the claim turns on attribution disputes (war / nation-state exclusion gray zone) or ransom negotiation outcomes, the IR roster is the moat that pays back the Lloyd's premium. War exclusion uses the 2024 Lloyd's market wording (Beazley led the post-NotPetya tightening) so the carrier-side risk-weighting is explicit but the claims-handling depth is what justifies the premium.
InsurTech mid-market specialist with attack-surface scan baked into the policy — the right pick when 'I want the carrier to find my pre-existing exposure BEFORE I apply so the pre-existing breach exclusion never triggers' dominates. At-Bay's continuous attack-surface scan is included in the premium so the carrier sees both the audit posture AND the technical posture at underwriting — operator-honest reduction of the 'knew or should have known' asymmetry that voids coverage on undisclosed findings. Sublimit structure: ransomware typically 50% of policy limit, social-engineering endorsement $250K-$1M depending on policy size, cyber-physical endorsement available. War / nation-state exclusion uses the 2024 Lloyd's market wording (consistent with Coalition + Beazley + Chubb post-NotPetya tightening). Reputation / brand recovery NOT covered (consistent with category).
Partnership-style carrier with pre-application security review that walks through exclusions explicitly — the right pick when 'I want the carrier to walk me through what's covered + what's excluded + what to add as endorsement BEFORE I sign' dominates. Resilience's pre-application security review is operator-honest unique in the category — the advisory team walks through the specimen policy + sublimit table + exclusion endorsements + recommends specific endorsement add-ons (cyber-physical · increased social-engineering · regulatory-fines coverage) based on the buyer's specific exposure profile. Sublimit structure: ransomware typically 50% of policy limit, social-engineering endorsement $250K-$1M, cyber-physical endorsement available. War / nation-state exclusion uses the 2024 Lloyd's market wording (consistent with the post-NotPetya tightening across the category).
Global enterprise carrier with bundle endorsement availability — the right pick when 'we already have Chubb commercial + we want cyber sublimits negotiated as part of the bundle' dominates. Chubb's cyber line ships standard sublimit structure: ransomware typically 25-50% of policy limit (conservative end of category), social-engineering endorsement $250K-$2M depending on policy size and bundle status, cyber-physical endorsement available for IoT/OT-exposed buyers. War / nation-state exclusion uses the 2024 Lloyd's market wording. The bundle-procurement advantage shows up at endorsement negotiation — existing Chubb commercial buyers can negotiate higher sublimits + broader endorsements as part of the multi-line MSA. Less aggressive than InsurTech carriers on default sublimits but stronger on bundle-stacked endorsement availability.
Global multinational carrier with elevated social-engineering endorsement headroom for regulated industries — the right pick when 'I'm a healthcare or payments multinational with material BEC exposure across multiple subsidiaries' dominates. AIG's regulated-industry placements often negotiate social-engineering endorsements up to $500K-$5M (vs $250K-$1M category default) reflecting AIG's traditional commercial-insurance strength in healthcare + payments + retail where BEC fraud sublimits are operator-load-bearing. Ransomware sublimit typically 25-50% of policy limit (conservative end of category, can negotiate higher on enterprise placements). Multinational regulatory-fines coverage handles cross-border GDPR + CCPA + state privacy law fines (where insurable by jurisdiction — GDPR fines structurally non-insurable in most EU member states). Cyber-physical endorsement available for IoT/OT-exposed multinational buyers.
US commercial insurance major with standard exclusions structure — the right pick when 'we already have Travelers commercial and want cyber sublimits as part of the bundle MSA' dominates. Travelers' cyber line ships standard sublimit structure: ransomware typically 25-50% of policy limit (conservative end of category), social-engineering endorsement $250K-$1M, cyber-physical endorsement available. War / nation-state exclusion uses the 2024 Lloyd's market wording. Less aggressive than InsurTech carriers on default sublimits + less bundle-endorsement flexibility than Chubb but the procurement-bundle story (5-15% bundle discount with existing Travelers commercial) wins for buyers with existing Travelers relationships.
SMB-focused carrier with clear exclusions language — the right pick when 'I'm sub-100 employees and I want exclusions written in plain English without enterprise complexity' dominates. Hiscox's cyber line ships SMB-appropriate sublimit structure: ransomware typically 50% of policy limit, social-engineering endorsement $100K-$500K (smaller sublimits matching SMB exposure profile), cyber-physical endorsement available. War / nation-state exclusion uses the 2024 Lloyd's market wording. The SMB-appropriate transparency is the operator-honest advantage — exclusions written in language the SMB buyer can actually read without a broker translator. Less sublimit headroom than enterprise carriers because the SMB risk profile doesn't justify it.
AI-driven SMB carrier with auto-detected exclusions structure — the right pick when 'I want the cheapest SMB cyber policy that still actually pays the claim within standard SMB sublimits' dominates. Cowbell's cyber line ships micro-SMB-appropriate sublimit structure: ransomware typically 50% of policy limit, social-engineering endorsement $100K-$250K (smallest sublimits in the category matching micro-SMB exposure profile). War / nation-state exclusion uses the 2024 Lloyd's market wording. AI-driven auto-detection reduces the application questionnaire burden but the buyer should still pull the specimen policy + sublimit table at quote time — the auto-detection underwrites the premium, not the buyer's understanding of what's covered.
European-anchored global carrier with GDPR-aware exclusions structure — the right pick when 'I'm a European multinational with cross-border NIS2 + DORA + GDPR exposure and I need a carrier that prices the European regulatory landscape into the sublimit table' dominates. Zurich's cyber line ships European-multinational-appropriate sublimit structure: ransomware typically 25-50% of policy limit, social-engineering endorsement $500K-$5M for European multinationals reflecting BEC sublimit headroom for material cross-border exposure. GDPR-fines coverage is structurally limited by jurisdiction — most EU member states make GDPR fines non-insurable as a matter of public policy, so the buyer needs to verify which subsidiary jurisdictions can actually insure regulatory fines vs which cannot. War / nation-state exclusion uses the 2024 Lloyd's market wording. Cyber-physical endorsement available for European IoT/OT-exposed multinational buyers (DORA-regulated financial services especially).
Most comparison sites refuse to forced-rank because their revenue depends on staying neutral. SideGuy ranks because it doesn't take vendor money. Here's the call by buyer persona.
Your problem: You're sub-50 employees pulling your first cyber quote. The broker is selling you on the headline policy limit. You know enough to ask 'what's the ransomware sublimit, what's the social-engineering sublimit, what's the cyber-physical endorsement, what about reputation damage' — and you want a carrier that surfaces the answers in plain English without a 60-page exclusions endorsement deep-read. Pair with the Compliance Authority Graph — early SOC 2 motion drops cyber premium 10-15% AND positions you better against the pre-existing breach exclusion.
Your problem: You're 50-200 employees. You've already had one social-engineering / BEC near-miss (a finance team member almost wired $200K to a deepfake-impersonated CEO). You want a cyber policy where the social-engineering sublimit actually covers your real BEC exposure — not the $250K default. Your CFO models a $1M-$3M BEC scenario and wants the sublimit to match.
Your problem: You're 200-1000 employees in manufacturing, healthcare with connected medical devices, utilities, transportation, or retail with connected store infrastructure. You have material IoT / OT / ICS exposure. The standard cyber policy excludes physical damage from cyber-mediated attacks unless you add the cyber-physical endorsement. Your CISO has modeled a worst-case scenario (hacked PLC bricks $500K equipment · ransomware shuts down production line · connected medical device compromise triggers patient safety event) and wants the endorsement scoped right.
Your problem: You're 1000+ employees building a structured cyber tower (e.g. $10M primary + $25M first excess + $50M second excess + $100M third excess). Each layer has its own sublimit table + exclusions endorsement. You're optimizing for: (1) ransomware sublimit headroom across the tower, (2) social-engineering endorsement covering material BEC exposure, (3) cyber-physical endorsement on the layers exposed to OT, (4) regulatory-fines coverage in jurisdictions where insurable, (5) war / nation-state exclusion language consistency across layers (carrier-side denial risk in attribution-disputed scenarios). See /operator cockpit for multi-substrate enterprise decisions.

Yes, fully intentional architecture across the entire 10-carrier category we cover. The coverage page is marketing — it tells the buyer what they bought in the language the buyer wants to hear. The exclusions endorsement is the actual contract — it tells the buyer what they DIDN'T buy in the language the carrier needs the policy to be enforceable in claims litigation. The 15:1 page ratio is structural across Coalition · Beazley · Chubb · AIG · At-Bay · Resilience · Cowbell · Travelers · Hiscox · Zurich. The buyer who reads the coverage page first and skips the exclusions endorsement is buying based on marketing; the buyer who reads the exclusions endorsement first and the coverage page second is buying based on the actual contract. The broker who reads the exclusions endorsement first IS the broker the buyer wants. The augmentation doctrine applied here: buy from whatever carrier you want — and SideGuy ships the parallel exclusions-comparison layer that pulls all 10 carrier specimen policies + sublimit tables + war exclusion wordings into one comparison sheet so the buyer can compare actual covered loss across quotes BEFORE binding. See Install Packs for productized scopes.
Because ransomware is structurally treated as a sub-coverage with its own sublimit cap, typically 25-50% of the headline policy limit across the 10 carriers we cover. The reasoning the carrier-side risk modeling uses: ransomware claims have higher loss ratios than other cyber claims (extortion + business interruption + restoration + IR + legal + notification all bundle into one event) so the carrier caps exposure per ransomware event below the headline limit. Pattern across the category: Coalition + At-Bay + Hiscox + Cowbell typically default 50% sublimit; Chubb + AIG + Travelers + Zurich typically default 25-50% sublimit; Beazley negotiates up to 100% of policy limit on enterprise placements; Resilience walks through the sublimit choice in pre-application review. The buyer should ALWAYS ask 'what's the ransomware sublimit on this quote' and model claim recovery scenarios against the SUBLIMIT not the headline limit. The headline policy limit is what the carrier markets; the sublimit table is what the buyer actually bought.
Merck v Ace American is the load-bearing precedent for war exclusion analysis in cyber insurance. NotPetya hit Merck in June 2017, caused $1.4B+ in damages, was attributed to Russian state actors. Ace American (now Chubb after the Chubb-Ace merger) denied coverage on the basis of the war exclusion in Merck's property policy. The New Jersey Superior Court ruled in 2022 that the war exclusion did NOT apply to NotPetya because the policy language pre-dated cyber-conflict drafting and the war exclusion was traditionally read to require physical military action between recognized governments. Merck won on appeal. Then the Lloyd's market and most major carriers REWROTE the war / nation-state exclusion language post-2022 (the 2024 LMA5564 family of clauses) to explicitly cover cyber-conflict scenarios — making the carrier MORE likely to deny coverage on the next NotPetya-shaped event. The buyer who signs a 2026 cyber policy is signing under the new exclusion regime, not the regime Merck won under. The honest 2026 read: war / nation-state attribution-disputed claims are higher-risk for buyer-side denial across the entire 10-carrier category. Beazley + AIG + Chubb + Zurich claims-handling depth on attribution-disputed claims matters more under the new exclusion regime than the policy language alone implies. Pair with the Breach Response Quality axis for IR roster depth comparison.
Because social-engineering / BEC fraud is structurally a hybrid loss — part cyber (the spoofed email or compromised account), part crime (the fraudulent funds transfer). Most carriers cover it under a separate endorsement or sub-coverage typically capped at $250K-$1M regardless of the headline policy limit. The operator-honest pattern: a $10M cyber policy that loses $3M to a BEC-mediated wire transfer pays $250K-$1M not $3M. Pattern across the category: Coalition + At-Bay + Hiscox typically $250K-$1M sublimit; Cowbell typically $100K-$250K sublimit (matching micro-SMB exposure); Beazley negotiates up to $1M-$5M on enterprise placements; AIG up to $500K-$5M for regulated industries; Chubb $250K-$2M depending on bundle status; Zurich $500K-$5M for European multinationals. Buyer should pull the social-engineering endorsement specifically + verify the sublimit + verify whether voice-impersonation + deepfake-mediated fraud are covered (most 2024+ policies still wording this — voice-cloning + generative-AI-mediated impersonation is a 2026 emerging coverage gap across the category). The buyer should ALSO carry crime / commercial crime insurance for the funds-transfer-fraud loss that exceeds the cyber social-engineering sublimit — cyber + crime are complementary not duplicative.
The 'knew or should have known' standard is the asymmetric weapon that carriers win every coverage dispute that turns on undisclosed pre-existing exposure. The carrier defines what the buyer 'should have known' AFTER the fact based on what their underwriting team would have flagged at application — typically anything an external attack-surface scan would have surfaced (exposed services, missing patches for known CVEs, weak email authentication, leaked credentials in public dumps). Operator-honest pattern: buyer applies for cyber policy, doesn't disclose the exposed RDP service they didn't know about, breach happens through that RDP service, carrier scans post-claim and finds the exposed service, denies coverage on pre-existing breach exclusion because the buyer 'should have known' (the scan would have surfaced it during application). The buyer should run their own external attack-surface scan (Bishop Fox · Praetorian · NetSPI · or the carrier's own scan if you're with Coalition Control / At-Bay scan / Resilience pre-application review) BEFORE applying so any finding is disclosed in the application. Disclosed findings with a remediation plan are FAR better positioned than undisclosed findings the carrier later discovers. The augmentation doctrine applied here: SideGuy ships the parallel pre-application scan + disclosure + remediation tracking layer that wires into whichever carrier the procurement team picks — see Install Packs for productized scopes.
Standard cyber policies cover data + privacy + extortion + business interruption + breach response from network attacks. They do NOT cover physical damage from cyber-mediated attacks unless the buyer adds an explicit cyber-physical endorsement. Pattern across the category: Coalition + At-Bay + Beazley + Chubb + AIG + Zurich + Resilience + Hiscox all offer cyber-physical endorsements (typically $5K-$25K extra premium for SMB-mid-market, custom for enterprise). The endorsement covers physical damage from cyber attacks on PLCs, SCADA systems, connected medical devices, building automation, OT/ICS infrastructure, IoT-connected store + warehouse + transportation infrastructure. Operator-honest pattern: manufacturing buyers, healthcare with connected medical devices, utilities, transportation, and retail with connected store infrastructure all hit this carve-out at claim time without the endorsement. The 2026 reality: standard cyber covers the data + IT side; cyber-physical endorsement covers the OT + IoT physical-damage side; property insurance covers the underlying physical asset; environmental + crime + business interruption may overlap depending on the loss type. The buyer needs all four coverage types coordinated — cyber alone leaves a structural gap on cyber-physical exposure. Pair with the SMB vs Enterprise Fit axis for coverage depth comparison.
Because reputation / brand recovery / lost-future-revenue is structurally NOT covered on any of the 10 carriers we cover despite vendor marketing implying it is. The actual coverage is forensics + breach notification + credit monitoring + PR firm engagement (typically $25K-$250K sub-limit) for the IMMEDIATE breach response. The long-tail brand damage + churned customer LTV + lost-deal pipeline that a public breach generates over 12-36 months falls outside the policy across the entire category. The carrier-side reasoning: long-tail brand impact is too difficult to measure objectively (causation + counterfactual + multi-factor attribution), too dependent on factors outside the buyer's control (media cycle + competitive response + macro conditions), and too easy for plaintiffs to inflate at claim time. The operator-honest framing: cyber pays for the IR + notification + immediate PR firm engagement; the buyer eats the brand + LTV + pipeline impact regardless of carrier. The honest 2026 read: don't buy cyber expecting it to cover lost-future-revenue — it covers the immediate response window only. Plan + budget for the long-tail brand recovery as an uninsured cost. Vendors that imply otherwise in marketing are misrepresenting what's actually in the specimen policy. The Mob Boss / Code War extension applied: the human element of being honest about what cyber actually covers vs what falls outside the policy is the moat — vendors structurally can't be that honest about their own product because it would surface the coverage gap that drives upsell to additional endorsements + complementary policies.
