In retail and e‑commerce, technology and security are inseparable from revenue. Your sales depend on checkout performance, your reputation depends on data protection, and your ability to scale depends on systems that don’t break when traffic surges. A single disruption—whether a cyberattack or a system failure—can stall orders, trigger chargebacks, and erode customer trust in hours.

Fusion Cyber Group solves this by combining the strengths of a Managed Security Service Provider (MSSP) and a Managed Service Provider (MSP). You get proactive cybersecurity and dependable IT management under one roof, with one accountable partner, and one set of outcomes: resilient operations, protected data, and confident growth.

We’ve supported Canadian SMBs and co‑managed enterprises since 1985 (incorporated in 2004), operating from Montréal with bilingual support. Our certified team (CEH, PNPT, OSCP, CISSP, CISA) works within the MITRE ATT&CK framework and the Lockheed Martin Cyber Kill Chain. And because aligned incentives matter, our fully onboarded clients are backed by a financially backed Cybersecurity Guarantee—if you’re breached, we fund the incident response, containment, and business recovery.

Revenue‑Focused Retail Security: Safeguarding the Customer Journey

Security earns its keep when it protects revenue at every step of the customer journey. We align controls to the stages your shoppers experience—from discovery to repeat purchase—so protection feels invisible to customers and powerful to attackers.

Attract: Keep Discovery Clean and Trustworthy

Customers first encounter your brand through ads, search results, and social posts. Attackers exploit this moment with malvertising and look‑alike domains designed to harvest credentials or card data. We combine brand‑monitoring with domain‑based message authentication to prevent spoofing and take down imposters quickly.

Search integrity matters as much as ad creative. If your site is flagged for malware or mixed content, organic traffic drops and paid ads become more expensive. We harden your CMS, validate third‑party scripts, and enforce change control so content updates don’t introduce risk. The result is a trustworthy first impression that converts.

Browse: Preserve Performance and Content Integrity

While shoppers browse, two forces shape conversion: speed and safety. Laggy product pages lower engagement; compromised pages leak data. We tune platform security controls—caching, WAF rules, and bot management—to accelerate the experience while blocking abuse. Script integrity monitoring helps prevent web skimmers from riding on legitimate third‑party libraries. When something looks off, our SOC sees it, investigates, and responds.

Price and inventory synchronisation across channels can introduce fragility. A failed API call should not break the page or expose keys. We standardise secrets management and scope permissions tightly so integrations do their job without opening doors.

Cart and Checkout: Stop Fraud Without Stopping Shoppers

Checkout is where threats concentrate. Bots test stolen cards; attackers attempt account takeover to drain stored balances; insiders might try privilege abuse. We layer controls—risk‑based authentication, velocity checks, device fingerprinting, and step‑up verification—so legitimate buyers sail through while suspicious activity triggers scrutiny or blocks.

Payment gateways and 3‑D Secure (3DS2) reduce chargeback risk, but poor tuning can add friction. We collaborate with your payment partners to calibrate thresholds and exemptions that fit your goods and customer profiles. Our focus is the same as yours: maximise approved transactions and minimise fraud losses.

Fulfilment and Post‑Purchase: Protect the Promise You Made

Once the order is placed, the brand promise shifts to fulfilment and communication. Attackers target warehouse systems and shipping notifications to pivot into accounts or deliver malware. We secure WMS and label‑printing flows, authenticate outbound email and SMS, and monitor for anomalies in tracking updates.

Returns are a favourite vector for friendly fraud. We instrument evidence trails—photos, timestamps, and serial numbers—so legitimate customers receive fast service while abuse patterns are detected and addressed. When disputes arise, you have the data to win them.

Loyalty and Retention: Guard the Long Tail of Value

Loyalty points and gift cards are liquid currency for criminals. We monitor balance‑check endpoints, enforce MFA for account changes, and watch for credential‑stuffing patterns that signal an impending wave of takeovers. Privacy preferences are enforced by design so marketing remains compliant and trusted.

A secure, smooth post‑purchase experience creates repeat buyers. We track signals—support contacts, delivery exceptions, redemption patterns—and feed them into your SIEM and analytics with appropriate safeguards so insights grow while risk stays contained.

MSSP Services: Protecting Retail & E‑Commerce Operations

Advanced Antivirus (AV) & Endpoint Detection and Response (EDR/XDR)

Retail endpoints aren’t only laptops—they’re POS terminals, kiosks, tablets, handheld scanners, and back‑office workstations. We deploy next‑generation AV with behavioural detection and EDR/XDR to see and stop malicious activity in real time. Telemetry flows to our SOC for correlation, so a suspicious script on a cashier’s terminal becomes an immediate alert, not a monthly report. We tune policies for performance so checkout stays snappy while protection stays strong.

Ransomware Detection and Containment

Ransomware targets what matters most: your ability to trade. We combine early‑stage detection (file entropy, process anomalies, privilege escalation) with automated containment (host isolation, credential revocation, and lateral‑movement blocking). Because every minute counts, our runbooks are rehearsed—who isolates which systems, who communicates status, and how we pivot to restore operations from immutable backups.

Advanced Email Protection & Anti‑Phishing

Most retail incidents start with a phish. We deploy layered email security to filter malware, spoofed domains, and business email compromise (BEC) attempts. We harden DMARC, SPF, and DKIM so your brand cannot be easily impersonated. We run ongoing phishing simulations and micro‑trainings so employees recognize lures, report them quickly, and feel confident doing so. The result is fewer credential thefts and fewer operational surprises.

Dark Web Monitoring

Compromised credentials and leaked data fuel account takeover and fraud. Our dark web monitoring tracks exposure of staff and executive emails, privileged accounts, and brand‑related domains. When we detect a leak, we trigger credential resets, step up authentication, and investigate the root cause. For retailers running loyalty programs, we also monitor for bulk credential dumps that could signal an imminent ATO wave.

Zero‑Trust Network Access (ZTNA)

Retail networks often blend staff devices, POS, guest Wi‑Fi, and IoT like cameras and sensors. Flat networks give attackers a freeway. We implement zero‑trust principles—authenticate every access, authorize least privilege, and assume breach. This means segmenting POS from office and guest traffic, enforcing identity‑aware policies for remote access, and validating device health before granting entry. ZTNA modernizes VPN‑style access with more granular control.

Proactive Threat Hunting

Attackers hide in the noise—odd PowerShell, suspicious service installs, unusual outbound connections. Our threat hunters look for faint signals that automated tools can miss, guided by the MITRE ATT&CK matrix. We hunt across endpoints, identities, and cloud logs, prioritizing tactics we see actively used against retailers and e‑commerce merchants. Every hunt produces hardening actions that reduce future noise.

SIEM and Centralized Logging

You can’t defend what you can’t see. We consolidate logs from endpoints, POS, firewalls, cloud apps, identity providers, and e‑commerce platforms into a SIEM for correlation and alerting. We tune detections to retail‑specific behaviours—suspicious gift‑card balance checks, sudden admin creation in your CMS, or repeated failed captures on a payment gateway. Centralized visibility shortens investigation time and provides the audit trail you need for compliance.

Vulnerability Management and Patch Orchestration

Attackers exploit known bugs because they work. We inventory assets, scan continuously for vulnerabilities, and orchestrate patching with minimal disruption to store hours and fulfilment windows. For systems that cannot be patched immediately, we add compensating controls—WAF rules, segmentation, or application allow‑listing—until the fix lands.

Data Loss Prevention (DLP) and Sensitive Data Controls

Retailers steward personal and payment data, plus loyalty and order information that criminals can monetise. We apply DLP to watch for sensitive data moving off network, leaving endpoints, or being uploaded to unmanaged cloud apps. Policies are pragmatic—protect the crown jewels without blocking legitimate workflows. We also standardise secure file transfer for vendors and partners.

DNS/Web Filtering and Brand Protection

We stop many threats before they start by blocking access to malicious domains, newly registered sites, and known phishing infrastructure. For brand protection, we monitor for look‑alike domains and takedown opportunities so customers aren’t tricked into fake stores during promotions.

Identity Security: MFA, SSO, and Least Privilege

Identity is the new perimeter. We enforce MFA everywhere it matters—admin consoles, remote access, finance systems, and cloud apps. We help you consolidate logins with single sign‑on (SSO) and role‑based access control so staff have exactly what they need, no more. We regularly review dormant accounts and privileges to close doors attackers love.

Penetration Testing and Red Team Exercises

Point‑in‑time assessments validate real‑world exposure. We perform scoped penetration tests against web apps, APIs, and internal networks, and we can simulate adversaries to test detection, response, and escalation paths. Findings translate to concrete, prioritised fixes—not just a report.

Digital Forensics and Incident Response (DFIR)

When something goes wrong, speed and clarity matter. Our DFIR team collects evidence, reconstructs the attack path, and contains the threat while business operations continue wherever possible. We coordinate with insurers and legal counsel, handle regulator‑ready documentation, and prepare clear communications for customers and partners. Our Cybersecurity Guarantee means you aren’t negotiating over hours in the middle of a crisis—we’re already engaged.

Backup, Disaster Recovery, and Business Continuity (BCDR)

Backups are your last line of defence. We implement 3‑2‑1 strategies with immutable, off‑site copies and frequent recovery tests. For e‑commerce, we design runbooks that prioritise order data integrity and payment reconciliation. For stores, we plan for POS continuity and offline fallback where possible. Business continuity plans specify who does what, when, and with which tools.

MSP Services: Reliable IT for Retail & E‑Commerce Needs

Proactive System Maintenance

We keep endpoints, servers, and network devices healthy with continuous monitoring, automated patching, and configuration management. Our goal is simple: your systems should feel boring because they just work. We time disruptive updates around trading hours to avoid impact.

Cloud, On‑Premise, and Hybrid Management

Most merchants run a hybrid stack—cloud e‑commerce, on‑premise POS, and SaaS for finance and marketing. We manage across these boundaries, aligning identity, access, and logging so you get a cohesive, secure environment. As you migrate workloads, we help you sequence changes to minimise risk and cost.

Helpdesk Support for Staff and Operations

Retail support must be fast and empathetic. Our helpdesk handles store and HQ issues with clear SLAs, triage playbooks, and escalation to specialists when needed. We train our team on retail context so they understand that “scanner not pairing” at 5 p.m. means orders won’t ship.

Backup & Disaster Recovery for Critical Data

From product images to ERP databases, we back up what you can’t afford to lose. Restore testing is routine, not exceptional. We also support e‑discovery and legal holds when required, with security controls to protect sensitive archives.

Vendor and Platform Management

We coordinate with your payment processors, POS vendors, e‑commerce platforms, 3PLs, and marketing tools. We track contract terms, escalate support tickets, and verify that changes don’t break security controls. When something fails, we convene the right parties and own resolution.

Network and Wi‑Fi That Match Retail Reality

Retail Wi‑Fi serves multiple audiences: staff, guests, and devices. We design for capacity and security—separate SSIDs and VLANs, strong encryption, and bandwidth management for guest networks. We monitor for rogue access points and unusual traffic. For stores, we also consider physical layout and interference from fixtures.

Change Management Without Red Tape

Retail moves fast. We balance agility with control through lightweight change management—documented changes, rollback plans, and post‑change validation. The result is fewer surprises and faster recovery if something behaves unexpectedly.

How We Work With Your Stack

E‑commerce platforms. Whether you run Shopify, Magento, WooCommerce, or a custom storefront, we harden admin access, integrate activity logs into the SIEM, and protect customer data flows. We help you deploy web application firewalls (WAF) and bot‑mitigation controls to reduce checkout abuse without harming legitimate shoppers.

POS and store systems. We segment POS networks, protect payment flows, and secure remote management tools. We monitor for suspicious device behaviour and ensure updates roll out safely across sites. For franchises and multi‑banner operations, we standardise baselines while allowing controlled local variation.

Back‑office and fulfilment. We connect ERP, WMS, CRM, and finance systems with identity and access controls. We prioritise uptime for order processing, label printing, and picking/packing tools. Where automation is fragile, we apply extra monitoring to spot failures before they cascade.

Integrations and APIs. Modern retail is APIs all the way down—marketplaces, loyalty, shipping, tax, and analytics. We audit API keys, rotate secrets, and monitor usage patterns for abuse. We help you adopt token‑based authentication and least‑privilege scopes.

Compliance Made Practical (PCI DSS, Privacy, and Email)

PCI DSS. We reduce the scope of PCI by segmenting cardholder data environments and hardening systems that touch payment data. We align logging, vulnerability management, and access control to PCI requirements and coordinate with your QSA (Qualified Security Assessor) when needed.

Privacy obligations. We treat personal information with privacy‑by‑design principles. That includes minimising data collection, securing consent records, and limiting who can access customer data. We also help operationalise subject access requests (SARs) with controls that verify identity and log disclosures.

Email and consent. We configure marketing systems to respect consent and suppression lists, and we protect transactional email channels from abuse. Authentication records (DMARC/SPF/DKIM) are maintained so mailbox providers trust your brand’s messages.

Compliance should support growth, not block it. We design controls that pass audits and keep teams productive.

Metrics That Matter (And We Report On)

• Mean Time to Detect (MTTD) / Respond (MTTR). We track how quickly we see and stop issues, and we drive those numbers down.
• Phishing resilience. Simulation results, reporting rates, and time‑to‑remediation after credential exposure.
• Endpoint health. Patch coverage, EDR agent status, and policy exceptions.
• Backup recoverability. Successful restore tests, RPO/RTO adherence, and immutable copy verification.
• Change stability. Incidents linked to changes and rollback effectiveness.
• Availability. Uptime for critical systems and latency at key user journeys (e.g., add‑to‑cart and checkout).
