    Do You Know You're Protected, Or Are You Just Hoping?*

    Most businesses with 10-100 computers have an MSP (Managed Service Provider). They assume they're protected because nothing bad has happened yet. But assumption isn't the same as evidence.

    The Question Every Business Owner Should Ask:

    If ransomware hit your network tomorrow morning, do you know you could recover, or are you hoping you could recover?

    Because there's a $4.5 million difference between those two answers.

    The Hard Reality:

    40%

    of backups fail when actually tested for recovery

    $4.5-10M

    Average ransomware attack cost for businesses with 10-100 computers (not just ransom—recovery, downtime, lost clients, reputation damage)

    60%

    of businesses hit with ransomware close within 6 months

    3+ weeks

    Average recovery time causing operational disruption

    Here's the Thing:

    Your MSP probably says "You're covered." They genuinely believe it. But they've likely never tested your backup recovery under attack conditions. They've never run a real vulnerability assessment. They assume you're protected because you haven't been hit yet.

    Hope is not a security strategy.

    The businesses that survive ransomware don't hope they're protected—they know they're protected because they've tested it, documented it, and proven it.

    Your network grew organically as your business succeeded. Now it's time to bring it all under control.

    You built a successful business—and your technology grew alongside it.

    Different computers purchased over the years. Various software solutions added as needed. Remote workers using their own devices. Cloud services adopted department by department.

    It worked... until it didn't.

    Now you're facing security gaps you didn't know existed, no clear picture of who has access to what, technology decisions made in silos, compliance requirements you can't easily prove, and the nagging feeling that "we should probably fix this."

    Does This Sound Familiar?

    We've added technology over the years, but nobody has the full picture

    We have security tools, but we're not sure if they're working together

    When someone leaves, we discover accounts and access we didn't know about

    We'd struggle to pass a security audit without weeks of prep work

    Different departments use different vendors and systems

    We've outgrown our startup IT approach—we need enterprise-grade security

    Already Working with an MSP (Managed Service Provider)?

    Most of our clients were too—until they discovered their MSP couldn't handle complex integrations, cloud services, or answer critical security questions.

    You're not looking to replace your IT person or MSP on a whim. Things are working... mostly.

    But lately, you've noticed:

    Red flags that your MSP may lack deep technical expertise:

    Vague answers when you ask specific technical questions

    No proactive outreach about emerging threats or technology changes

    Can't explain how your backup would actually work in a ransomware attack

    Struggles with complex system integrations across your platforms

    No regular security assessments or vulnerability testing

    "We've got you covered" without showing you what that means

    Reactive support only—waiting for problems instead of preventing them

    Limited cloud services expertise as your business moves to cloud

    There's a difference between an MSP and an MSSP (Managed Security Services Provider).

    Your current MSP might be great at password resets and printer issues. But when you need complex network architecture, seamless system integrations across diverse platforms, cloud migration expertise, or you face regulatory compliance questions—you need an MSSP with deep security expertise, not just IT support.

    Quick Test: Do You Know, Or Are You Hoping?

    Ask your current MSP these questions. Their answers will tell you everything:

    "If ransomware encrypted our files tomorrow, walk me through exactly how you'd recover our data. When was the last time you tested that process?"

    "What security vulnerabilities currently exist in our network? Show me the last vulnerability assessment report."

    "If ransomware hit us and we couldn't operate for 3 weeks, what's the financial impact to our business? What's your liability?"

    Vague answers = hoping. Specific, documented answers = knowing.

    The Transition Reality:

    "Won't switching be disruptive and expensive?"

    No. Here's how we handle transitions:

    1. Assessment Phase

    We audit your current setup (often working alongside your existing MSP initially)

    2. Gap Analysis

    We show you exactly what's missing and what's working fine

    3. Phased Approach

    Technical upgrades first, full transition only if it makes sense

    4. Zero Disruption

    Your team won't notice the switch—better protection, same (or better) support

    Many clients keep their existing MSP for day-to-day support while we handle the complex technical infrastructure and security.

    What an MSSP (Managed Security Services Provider) Delivers:

    Unlike traditional MSPs focused on IT support, we provide security-first expertise:

    Deep Network Architecture Expertise

    50 years designing and securing networks—from Royal Bank of Canada to Internet protocols to modern cloud infrastructure

    Complex System Integration Mastery

    Protection track record maintained

    Professional approach vs. typical IT provider: Most IT providers are generalists who handle IT support and treat security as an add-on. We're security specialists who've been protecting businesses from evolving threats since 1988.

    Proactive prevention vs. reactive response: While typical IT providers wait for problems and then respond, our deep experience enables us to anticipate threats, test recovery procedures monthly, and prevent incidents before they occur.

    Documented processes vs. hope: We don't just implement security tools—we document everything, test recovery regularly, and provide evidence-based assurance. You'll know you're protected, not just hope you're protected.

    Strategic security architecture: Decades of experience since 1988 means we've seen every attack vector, every failure mode, and every recovery scenario. We architect security based on real-world lessons, not vendor marketing materials.

    Why Enterprise-Grade Technology Matters

    Cloud-Based Integrated Protection

    Unlike hardware-limited solutions, our cloud-based security creates multiple layers of protection for users and devices both on and off your network. Web filtering combined with advanced computer protection ensures comprehensive coverage wherever your team works.

    Why it matters: Most IT providers use affordable hardware-based solutions that can't protect remote workers. Our cloud-first approach covers everyone, everywhere.

    Advanced Threat Detection & Response

    Advanced detection provides rapid detection, containment, and removal of advanced threats that bypass traditional antivirus. Our systems catch what others miss.

    Why it matters: Consumer-grade antivirus only stops known threats. Advanced detection watches behavior and stops sophisticated attacks that traditional antivirus misses.

    Global Threat Intelligence Network

    Our security is backed by one of the world's largest threat intelligence teams, analyzing billions of daily security events globally to expose and block emerging threats before they reach you.

    Why it matters: Threats evolve hourly. Hardware-based solutions can't update fast enough. Cloud-delivered intelligence protects against zero-day attacks in real-time.

    Cloud-Based Network Security

    Modern cloud-based networking and security services move beyond traditional data center-centric models. Provides consistent security for all users accessing cloud apps and the internet from any location.

    Why it matters: Traditional firewalls only protect your office. Cloud security protects everywhere—home, coffee shop, airport—with the same enterprise-grade security.

    Predictive Threat Intelligence

    Advanced AI tracks connections between threats and malicious websites to predict and prevent cyber attacks before they reach your systems. Automatically identifies attacker infrastructure being prepared for future attacks.

    Why it matters: Most security reacts after you're attacked. Predictive intelligence stops threats before they launch—blocking malicious websites days or weeks before attacks begin.

    Global Cloud Architecture

    Global cloud infrastructure with automated failover and 100% uptime. Routes requests to closest datacenter, cutting network latency by up to 73% compared to traditional security solutions. No added latency during security checks.

    Why it matters: Hardware-based security slows down your network. Cloud-delivered security actually improves performance while providing superior protection.

    Web Address Blocking

    Web filtering blocks threats before they reach your network or devices. Works at office or remotely, providing the first line of defense that stops threats before connections are ever established.

    Why it matters: Traditional security waits until threats reach your network. Web filtering stops malicious connections before they start—preventing downloads, callbacks, and data theft.

    Industry-Leading Detection Rate

    Highest cyberthreat detection rate in the industry, protecting 100+ million users globally and 30,000+ companies. Enterprise-grade protection previously available only to Fortune 500 organizations.

    Why it matters: Detection rate determines what gets through. The highest detection rate means fewer successful attacks, less downtime, and lower breach risk.

    Enterprise-Grade Security Tools

    Our security platform uses enterprise tools that meet SOC 2 Type II compliance standards with comprehensive auditing and transparent security controls. These tools provide the documented security practices needed to support your compliance requirements (HIPAA, PCI DSS, etc.).

    Why it matters: Compliance auditors and insurers require documented controls. Using SOC 2 compliant security tools provides the audit trail and documented controls they demand.

    Automated Patch Management

    Automated patching across Windows, macOS, Linux, and 200+ third-party applications. Organizations face 2,000-4,500 security patches monthly—manual tracking is impossible. Our system automatically tests, schedules, and deploys critical security updates before vulnerabilities can be exploited.

    Why it matters: 60% of breaches exploit known vulnerabilities with available patches. Most IT providers rely on manual patching that leaves critical gaps for weeks. Automated enterprise patch management closes security windows within hours, not months.

    Unknown Program Blocking (Maximum Protection Tier)

    Blocks ALL unknown programs from running—the opposite of antivirus which only blocks known-bad software. This prevents brand new attacks, ransomware variants, and new threats that traditional antivirus has never seen before.

    Why it matters: Antivirus relies on signatures of known threats—if it's new or unknown, it runs. We say "if we haven't approved it, it's blocked." This stops 100% of unknown threats, including AI-created attacks and constantly-changing ransomware that evades traditional detection.

    For the first time, enterprise-grade software and services are available to businesses with 10-100 computers. Previously, only enterprises (1,000+ employees) could access these sophisticated security tools. Unlike consumer-grade or affordable hardware-based equipment used by typical IT providers, our integrated cloud-delivered solutions provide superior threat detection, global threat intelligence, and protection for remote workers. Transparent pricing. Flexible contract options. All costs disclosed upfront.

    *CMMC/NIST 800-171 plans may have an additional charge.
