the Big 4 invoice.

Companies with 50 to 1,000 employees occupy the cybersecurity industry’s most underserved segment. Too large for SMB-targeted tooling, too small for enterprise consulting engagements, and frequently stuck choosing between Big 4 overhead and inexperienced regional firms. Adversim was built specifically for this segment. Senior practitioners. Fixed-fee pricing. US-based delivery. The cybersecurity firm the mid-market actually deserves.

// Why Corporate & Mid-Market Is Different

The mid-market is uniquely underserved.

Mid-market companies — typically defined as 50 to 1,000 employees and $10M to $1B in revenue — sit in the cybersecurity industry’s most underserved segment. You’re too large for the cybersecurity tooling and managed service offerings that target the SMB market. You’re too small to economically engage Big 4 consultancies whose pricing models assume enterprise budgets. And you’re often stuck choosing between regional firms with inconsistent expertise and national firms whose senior practitioners pitch the work but disappear before delivery starts.

Meanwhile, the cybersecurity expectations you face have multiplied. Enterprise customers require SOC 2 reports. Cyber insurance underwriters require demonstrated controls. M&A diligence increasingly includes cybersecurity assessment. Board members ask sophisticated cyber questions that internal teams can’t always answer. Regulators expect documented programs. And the threat actors don’t care that you don’t have a CISO — your data and operations are just as attractive a target as the F500 organizations they also pursue.

Adversim was built for this segment. Our entire business model is designed around the mid-market’s actual constraints and expectations: senior-only delivery (no bait-and-switch with junior staff), fixed-fee pricing (no T&M anxiety), US-based work (no offshore handoffs), 48-hour proposals (no consulting theater wasting your buying cycle), and engagement scoping that matches your stage and budget instead of maximizing firm revenue. We work across virtually every industry vertical, with deep specialization in regulated sectors but practical applicability to general commercial mid-market organizations as well.

The mid-market doesn’t need a bigger firm. It needs a better one. That’s the entire premise of Adversim.

// Corporate & Mid-Market Threat Landscape

Six threats defining
corporate & mid-market cybersecurity
right now.

Observed attacker behavior, not theoretical risk.

// THREAT 01 — RANSOMWARE

Mid-Market Ransomware

Mid-market organizations are disproportionately targeted by ransomware operators because they often have valuable data and operations but lack the security investment of larger enterprises. Average mid-market ransomware impact routinely exceeds $1M including downtime, remediation, ransom (if paid), and remediation costs.

// THREAT 02 — BEC

Business Email Compromise

BEC remains the highest-dollar-loss cyber threat for mid-market organizations. Wire fraud through compromised email accounts, vendor impersonation, and executive-targeted phishing campaigns cost mid-market companies billions annually. Process and verification controls are the difference between catching and missing these attacks.

// THREAT 03 — CUSTOMER REQS

Customer-Driven Compliance

Enterprise customers increasingly require their mid-market vendors to demonstrate cybersecurity through SOC 2, ISO 27001, or industry-specific certifications. The work is non-discretionary — it gates revenue. Most mid-market companies underestimate the time required and start too late.

// THREAT 04 — CYBER INSURANCE

Cyber Insurance Tightening

Cyber insurance underwriting for mid-market companies has become substantially more rigorous. Carriers now require evidence of MFA, EDR, backup integrity, and incident response readiness. Renewals are denied or substantially repriced when controls don’t meet evolving expectations.

// THREAT 05 — M&A

M&A Cybersecurity Diligence

M&A activity increasingly includes cybersecurity diligence — both buyers requiring it of acquisition targets and sellers needing to demonstrate posture during sale processes. Discovered cybersecurity issues can affect valuation, deal terms, or transaction timing.

// THREAT 06 — THIRD-PARTY

Vendor & Supply Chain Risk

Mid-market organizations typically depend on dozens of SaaS vendors, MSPs, and service providers. Each is a potential attack path with limited visibility into vendor security posture. The Crowdstrike incident demonstrated how single-vendor compromise can cascade — and made vendor risk a board-level concern.

// The Mid-Market Cybersecurity Problem

Why the mid-market is structurally underserved.

The mid-market’s cybersecurity problem isn’t fundamentally a budget problem — most mid-market organizations can afford appropriate cybersecurity investment when they understand what to buy. The problem is a market structure problem: the cybersecurity consulting industry is bifurcated between firms optimized for the F500 and firms optimized for the SMB, with the mid-market falling between.

Why Big 4 doesn’t actually work for the mid-market

Big 4 firms (and the Big-4-adjacent national consultancies that compete with them) optimize for enterprise engagements. Their pricing models assume enterprise budgets. Their delivery models assume multi-tier staffing with senior partners pitching and junior staff delivering. Their proposal cycles take weeks. Their reports follow enterprise templates that are often disconnected from the actual environment they describe. None of this is malicious — it’s an entirely rational response to the economics of serving F500 clients. But it doesn’t fit mid-market budgets, timelines, or operational realities.

Why SMB-focused firms don’t scale up

Firms optimized for SMB tend to focus on tooling resale, managed security services, and high-volume low-touch engagement models. Their senior expertise is often spread thin across many clients. Their assessment products tend toward standardized templates that don’t accommodate the complexity of mid-market environments. And their strategic advisory capability is frequently limited — they’re built to deliver tools and managed services, not the senior strategic guidance mid-market organizations increasingly need.

The Adversim middle

Adversim was deliberately built for the segment between these extremes. Senior-led delivery (because mid-market organizations have nuanced environments that require experienced judgment). Fixed-fee pricing (because mid-market budgets need predictability). US-based work (because data sovereignty and quality consistency matter). 48-hour proposals (because mid-market buying cycles don’t accommodate Big 4 sales theater). Engagement scope calibrated to your stage and budget rather than firm revenue maximization.

Most of our clients work with us year over year through some combination of annual penetration testing, periodic assessment refreshes, and vCISO advisory. The relationship model is partnership, not transaction.

// Corporate & Mid-Market Cybersecurity FAQ

Straight answers
for corporate & mid-market.

Companies with approximately 50 to 1,000 employees and $10M to $1B in revenue. We have clients outside that range — both smaller and larger — but our entire business model is designed around the operational realities of mid-market organizations. Companies in this range typically face the most underserved cybersecurity consulting market in the industry, and we built Adversim specifically to address it.
Two structural differences. First, we’re typically about 20% below Big 4 rates while delivering senior-only work — possible because we don’t carry Big 4 overhead (large office leases, layered management, sales engineering teams that never see your environment). Second, all our pricing is fixed-fee. You know the price up front, with assumptions written into the proposal — no T&M ambiguity, no scope-creep change orders, no surprise invoices at the end of the month.
Most mid-market penetration tests run $15,000 to $50,000 depending on scope. A focused external test runs $15,000-$25,000. Comprehensive engagements covering external, internal, key applications, and cloud infrastructure typically run $30,000-$50,000. Red team operations and multi-environment engagements scale higher. All pricing is fixed-fee.
Yes. Cyber insurance underwriting has tightened substantially and most mid-market organizations face increasingly rigorous control requirements at renewal. We perform the underlying penetration testing, control assessments, and posture documentation that satisfies underwriter expectations. The work frequently results in better renewal terms or premium reductions that exceed the engagement cost.
Yes. We do both buy-side and sell-side cybersecurity diligence. Buy-side: assessing acquisition target cybersecurity posture, identifying deal-impacting findings before they surface in legal due diligence. Sell-side: preparing target companies’ cybersecurity posture for diligence questions buyers will ask. Both engagements are typically scoped for tight transaction timelines (2-4 weeks).
vCISO engagements typically run $4,000 to $20,000 per month depending on bandwidth. A 4-hour-per-month executive advisory engagement is at the low end; a 20+ hour-per-month engagement where the vCISO functions as interim head of security is at the high end. Most mid-market engagements settle around 8-12 hours per month at $6,000-$12,000 monthly retainer.
Proposals are typically delivered within 48 hours of a scoping call. Once signed, most engagements kick off within 1-2 weeks. Rush scheduling is available for incident-driven situations, cyber insurance deadlines, or customer-required timelines.
No. Adversim is a proactive cybersecurity practice. We do not perform active incident response, live breach containment, or digital forensics. We focus on readiness — penetration testing, risk assessments, tabletops, ransomware readiness, and the program-level work that prepares mid-market organizations for incidents before they occur. As part of readiness work, we help you identify and onboard a qualified DFIR partner in advance.
