Updated on December 12, 2025, by Xcitium

What if one of the biggest shopping days of the year was also one of the biggest opportunities for cybercriminals? That’s exactly why understanding what Cyber Monday is goes far beyond discounts and deals. For businesses, IT managers, and cybersecurity leaders, Cyber Monday represents both massive revenue potential and elevated digital risk.

Cyber Monday is no longer just an online shopping event. It’s a high-traffic, high-threat digital environment where attackers actively exploit consumer urgency, weak security controls, and unprepared organizations. If you’re responsible for protecting systems, data, or customers, understanding what Cyber Monday is—and why it matters to cybersecurity—has never been more critical.

This guide breaks down what Cyber Monday is, how it evolved, why it matters to modern organizations, and how cybersecurity teams can stay ahead of threats during one of the busiest digital days of the year.

What Cyber Monday Is and How It Started

At its core, Cyber Monday is an annual online shopping event that takes place on the Monday following Thanksgiving in the United States. It was first introduced in 2005 by the National Retail Federation to encourage consumers to shop online after the Thanksgiving weekend.

The idea was simple: people returned to work on Monday, had access to faster internet connections, and were more likely to shop online. What started as a marketing initiative quickly became one of the most profitable eCommerce days globally.

Today, Cyber Monday is a global digital commerce phenomenon, generating billions of dollars in online sales across retail, software, SaaS, and B2B services.

Key Characteristics of Cyber Monday

Online-only or digital-first promotions
Heavy reliance on web, mobile, and cloud infrastructure
Massive spikes in traffic and transactions
Increased exposure to cyber threats

Understanding what Cyber Monday is means recognizing it as both a commercial and cybersecurity event.

Why Cyber Monday Matters More Than Ever in 2026

Cyber Monday has evolved far beyond retail discounts. It now impacts industries such as:

Software and SaaS
Cloud services
Cybersecurity platforms
Managed IT services
B2B technology vendors

For many organizations, Cyber Monday traffic rivals or exceeds normal peak usage. That makes it a prime target for cybercriminals.

Why attackers love Cyber Monday

Users are distracted and rushed
Businesses prioritize uptime over security
IT teams are stretched thin
Phishing campaigns blend in with legitimate offers

When discussing what Cyber Monday is today, it must be framed as a high-risk, high-reward digital environment.

The Cybersecurity Risks Behind Cyber Monday

One of the most overlooked aspects of understanding what Cyber Monday is involves recognizing the security threats tied to it. Every surge in online activity creates opportunities for exploitation.

Common Cyber Threats During Cyber Monday

1. Phishing and Fake Promotions

Attackers create realistic emails, ads, and landing pages that mimic legitimate Cyber Monday deals. These scams steal:

Login credentials
Payment information
Corporate email access

2. Malicious Websites and Fake Stores

Fake eCommerce sites appear overnight, often ranking through ads or compromised SEO. These sites are designed to harvest payment data or distribute malware.

3. Credential Stuffing Attacks

Cybercriminals use leaked credentials to attempt logins at scale, targeting:

Customer portals
Admin dashboards
SaaS platforms

4. Ransomware and Supply Chain Attacks

During Cyber Monday, attackers exploit third-party vendors, plugins, and integrations that businesses rely on to operate at scale.

Understanding what Cyber Monday is from a security standpoint means acknowledging that threat activity spikes dramatically.

Why IT Managers and CISOs Should Care

For IT managers and cybersecurity leaders, Cyber Monday isn’t just a marketing date—it’s a stress test for infrastructure and security posture.

Cyber Monday exposes:

Weak endpoint protection
Poor email security controls
Insufficient zero-trust policies
Unpatched systems and applications

If your organization supports eCommerce, SaaS, or customer portals, Cyber Monday is when vulnerabilities are most likely to be exploited.

Knowing what Cyber Monday is helps leaders proactively prepare instead of reacting to incidents.

How Businesses Can Prepare for Cyber Monday Securely

Preparation is the difference between success and disruption. A strong security posture ensures uptime, customer trust, and brand reputation.

Cybersecurity Best Practices for Cyber Monday

1. Strengthen Endpoint Security

Ensure all endpoints are protected with advanced threat detection, not just signature-based antivirus.

2. Harden Email Security

Deploy phishing-resistant email security solutions to stop malicious Cyber Monday campaigns before they reach users.

3. Implement Zero Trust Access

Limit access by verifying identity continuously, especially for privileged users and admins.

4. Monitor Traffic in Real Time

Use real-time monitoring to identify abnormal traffic spikes, bot activity, or attempted breaches.

5. Prepare Incident Response Plans

Cyber Monday is not the time to improvise. Ensure response plans are tested and teams are on standby.

Understanding what Cyber Monday is includes planning for both business growth and security resilience.

The Role of AI and Automation During Cyber Monday

AI-driven security tools are becoming essential during Cyber Monday. Manual processes cannot keep up with the scale and speed of modern attacks.

Benefits of AI-powered cybersecurity

Faster threat detection
Automated containment
Reduced false positives
24/7 monitoring during peak periods

As Cyber Monday continues to grow, automation becomes a necessity—not a luxury.

Cyber Monday for B2B and SaaS Companies

Cyber Monday is no longer limited to consumer retail. Many B2B and SaaS organizations offer:

Subscription discounts
Enterprise promotions
Free trials and onboarding offers

This creates additional risks:

Increased account creation fraud
Abuse of trial systems
Attacks on APIs and authentication flows

Understanding what Cyber Monday is for SaaS means securing:

Identity and access management
APIs and integrations
Customer onboarding workflows

Cyber Monday and Consumer Trust

Trust is fragile. One breach during Cyber Monday can undo years of brand building.

Customers expect:

Secure checkout
Data privacy
Fraud prevention
Transparent communication

Organizations that invest in security during Cyber Monday gain a competitive advantage by protecting both revenue and reputation.

The Future of Cyber Monday and Cybersecurity

Cyber Monday will continue to expand globally, with:

More mobile shopping
Greater cloud reliance
Increased automation
Smarter cyber threats

The question is no longer what Cyber Monday is, but how prepared organizations are to operate securely during it.

Security leaders who treat Cyber Monday as a strategic event—not just a sales day—will be better positioned for long-term success.
