MSSP · Chicago metro
Cybersecurity services in Chicago — 24/7 SOC, MDR, MSSP.
EFROS is a cybersecurity-first MSSP for Chicago-area small and mid-size businesses. A 24/7 Security Operations Center, managed detection and response, email/BEC defense, vCISO leadership, and a bundled incident response retainer — under one accountable SLA.
Serving Cook, DuPage, Lake, Will, and the collar counties since 2009. The security partner Chicago's logistics, freight, and operational businesses trust when a breach would stop revenue.
The threat
What's actually hitting Chicago SMBs
The four attack patterns that drive nearly every loss we see in the 25–300 employee band — and the controls that stop each one.
Ransomware priced to your weekly revenue
Operators study your business before they strike and set the ransom against what a week of downtime costs you. Chicago's logistics, manufacturing, and professional-services firms are squarely in the target band. Prevention plus tested recovery is the only answer that holds.
Business email compromise & wire fraud
A spoofed vendor or executive email reroutes a payment, or a rate-confirmation gets altered before a load moves. BEC is the highest-dollar attack most SMBs face, and it lands in the inbox — which is why EFROS leads with email/BEC defense, not antivirus.
Identity & MFA-fatigue attacks
Attackers buy credentials and spam push prompts until someone taps approve. Conditional Access, phishing-resistant MFA, and 24/7 identity monitoring close the gap that endpoint tools alone can't see.
Vendor & supply-chain blast radius
Your TMS, ELD, EDI, or SaaS vendor gets breached and you inherit the exposure through an over-scoped OAuth grant. EFROS monitors third-party token scopes and anomalous grants — the attack path most MSPs never look at.
The program
Managed cybersecurity, end to end
Engage EFROS as your full MSSP, or as the security layer behind your existing IT. Either way you get the same operating stack.
24/7 SOC + MDR
Watched around the clock
24/7/365 Security Operations Center coverage with SIEM-driven detection and response, SentinelOne endpoint detection, and pre-authorized containment. Threats get triaged and contained while you sleep — not queued for Monday.
Email / BEC defense
Stop the inbox attack
DMARC, SPF, and DKIM enforcement, anti-impersonation rules, lookalike-domain monitoring, and freight-grade controls against rate-confirmation and factoring fraud. Plus phishing simulation and security awareness training.
vCISO & compliance
Direction + documentation
Fractional security leadership, cyber-insurance-renewal support, and audit-ready reporting. SOC 2-aligned and ISO 27001-aligned with controls mapped to NIST CSF 2.0 — the governance your board and your carrier ask for.
Explore the building blocks: SOC as a Service, MDR, vCISO, and Microsoft 365 security.

Questions
Chicago cybersecurity — frequently asked
Is EFROS an MSSP or an MSP?
Both, and that is the point. EFROS is a cybersecurity-first MSP/MSSP: we run the full managed-IT stack and the managed-security stack under one accountable SLA. You can engage us purely for security (24/7 SOC, MDR, vCISO, email defense) on top of your existing IT, or for the complete IT + security program. Most Chicago SMBs in the 25–300 employee band find the bundled program both cheaper and tighter than stitching an MSP and a separate MSSP together.
Do you have a Chicago SOC, or is it remote?
Our 24/7 SOC is delivered remotely by design — security operations should never depend on whether an analyst can get to a building during a snowstorm. We serve the Chicago metro (Cook, DuPage, Lake, Will, Kane, and the collar counties) and dispatch on-site for work that needs physical access. You get continuous, enterprise-grade monitoring without paying for local overhead.
We have an internal IT person but no security team. Can you just be the security layer?
Yes — that is our co-managed model. Your IT lead keeps running day-to-day IT, and EFROS sits behind them as the 24/7 SOC, MDR, email defense, vCISO, and incident-response bench. Your team retains control while gaining enterprise security tooling and senior analysts without three new full-time hires.
Can you help us pass a cyber-insurance renewal or a customer security questionnaire?
Yes. Carriers and enterprise customers now require MFA, EDR, 24/7 monitoring, email authentication, tested backups, and a documented incident-response plan. EFROS operates SOC 2-aligned and ISO 27001-aligned with controls mapped to NIST CSF 2.0 and produces audit-ready reporting that answers those questionnaires directly. To be precise: we provide readiness and aligned controls — we are not a certification body and do not issue certifications.
We're a freight broker / carrier / 3PL. Do you understand our risk?
Deeply. Transportation and logistics is the EFROS core vertical. We defend against freight-specific fraud — rate-confirmation spoofing, factoring-email isolation, fictitious pickups, and load-board credential theft — and we harden the TMS/ELD/EDI stack. See our cargo-fraud-defense program for the full picture.
What if we're being attacked right now?
If you have an active security incident, do not wait on this page — go to our incident-response line. EFROS offers a bundled Incident Response retainer with a guaranteed 4-hour response SLA and a named incident commander for clients, and emergency engagement for new contacts in crisis.
