Why Data Breaches Happen: 9 Common Causes and How Akamai Helps Prevent Them

Jul 14, 2026

Every organization relies on digital infrastructure to run its business from websites and cloud applications to APIs and remote work environments. While these technologies improve productivity and customer experience, they also expand the attack surface for cybercriminals. 

Data breaches are no longer limited to large enterprises. Businesses of all sizes face growing risks from ransomware, phishing attacks, stolen credentials, insecure APIs, and cloud misconfigurations. According to multiple cybersecurity reports, attackers increasingly exploit human error and identity-based attacks rather than sophisticated hacking techniques. 

Understanding why data breaches happen is the first step toward building a stronger cybersecurity strategy. Equally important is adopting security solutions that proactively stop threats before they become incidents. 

This is where Akamai Security Solutions help organizations strengthen their defenses through Zero Trust access, API security, Web Application Firewall (WAF), DDoS protection, and continuous threat intelligence. 

Why Data Breaches Continue to Increase 

Modern businesses store sensitive customer information, financial records, intellectual property, and operational data across multiple cloud platforms and applications. 

Unfortunately, traditional perimeter security is no longer enough. 

Today's IT environments include: 

  • Remote employees  
  • Cloud workloads  

  • SaaS applications  

  • Mobile devices  

  • APIs  

  • Third-party integrations  

Each connection introduces new opportunities for attackers. 

Organizations that rely solely on firewalls or antivirus software often leave significant security gaps that cybercriminals actively exploit. 

9 Common Reasons Data Breaches Happen 

1. Weak or Stolen Credentials 

Passwords remain one of the easiest ways for attackers to gain unauthorized access. 

Employees frequently: 

  • Reuse passwords  

  • Choose weak passwords  

  • Fall victim to phishing attacks  

  • Store credentials insecurely  

Once attackers obtain login credentials, they can access sensitive systems without triggering traditional security alerts. 

How Akamai Helps 

Akamai strengthens identity security using: 

  • Zero Trust Network Access (ZTNA)  

  • Multi-Factor Authentication (MFA)  

  • Adaptive authentication  

  • Continuous user verification  

Instead of trusting users after login, Akamai continuously validates identity throughout every session. 

2. Phishing and Social Engineering 

Cybercriminals increasingly target employees rather than technology. 

Phishing emails often appear legitimate and trick users into: 

  • Revealing passwords  
  • Downloading malware  
  • Opening malicious attachments  
  • Approving fraudulent login requests  

One successful phishing email can compromise an entire organization. 

How Akamai Helps 

Akamai reduces phishing-related risks through: 

  • Identity-aware access controls  
  • Risk-based authentication  
  • Behavioral analytics  
  • Least-privilege access  

Even if credentials are stolen, attackers face additional verification and access restrictions. 

3. Insecure APIs 

APIs connect applications, websites, mobile apps, and cloud services. 

Unfortunately, unsecured APIs have become one of the fastest-growing attack vectors. 

Common API vulnerabilities include: 

  • Broken authentication  
  • Excessive data exposure  
  • Weak authorization  
  • Injection attacks  
  • Automated abuse  

How Akamai Helps 

Akamai API Security provides: 

  • API discovery  
  • Continuous monitoring  
  • Bot detection  
  • Runtime protection  
  • API abuse prevention  

Organizations gain complete visibility into known and shadow APIs before attackers exploit them. 

4. Misconfigured Cloud Infrastructure 

Cloud environments offer flexibility but can also introduce security risks when configured incorrectly. 

Examples include: 

  • Publicly exposed storage buckets  
  • Open databases  
  • Overly permissive permissions  
  • Poor network segmentation  

Many breaches occur because systems are accidentally left accessible to the How Akamai Helps public internet. 

Akamai improves cloud security through: 

  • Zero Trust architecture  
  • Network segmentation  
  • Secure application delivery  
  • Continuous policy enforcement  

These controls reduce exposure and limit lateral movement. 

5. Ransomware Attacks 

Ransomware continues to evolve rapidly. 

Attackers typically: 

  • Gain initial access  
  • Escalate privileges  
  • Encrypt business-critical systems  
  • Demand ransom payments  

Many modern ransomware groups also steal sensitive data before encryption. 

How Akamai Helps 

Akamai helps minimize ransomware risk with: 

  • Microsegmentation  
  • Identity-based access  
  • Threat detection  
  • Network isolation  

Even if one endpoint is compromised, attackers cannot easily spread throughout the network. 

6. Distributed Denial-of-Service (DDoS) Attacks 

DDoS attacks flood websites or applications with massive traffic volumes, making services unavailable. 

Although DDoS attacks may not always steal data directly, they often serve as distractions while attackers launch other malicious activities. 

How Akamai Helps 

Akamai operates one of the world's largest edge platforms capable of absorbing massive DDoS attacks before they reach business infrastructure. 

Protection includes: 

  • Layer 3 protection  
  • Layer 4 protection  
  • Layer 7 application protection  
  • Real-time traffic filtering  
  • Global threat intelligence  

7. Vulnerable Web Applications 

Outdated web applications remain attractive targets. 

Common vulnerabilities include: 

  • SQL Injection  
  • Cross-Site Scripting (XSS)  
  • Remote Code Execution  
  • File inclusion attacks  
  • Authentication flaws  

Without regular updates and protection, attackers can exploit these weaknesses to access databases and customer information. 

How Akamai Helps 

Akamai Web Application Firewall (WAF): 

  • Blocks OWASP Top 10 attacks  
  • Protects against zero-day threats  
  • Monitors malicious traffic  
  • Prevents automated exploitation  

Applications remain protected even before patches are deployed. 

8. Insider Threats 

Not every breach comes from external hackers. 

Insider threats may involve: 

  • Disgruntled employees  
  • Negligent users  
  • Third-party contractors  
  • Excessive user permissions  

Unauthorized access often goes unnoticed because insiders already possess valid credentials. 

How Akamai Helps 

Akamai enforces: 

  • Least privilege access  
  • Role-based permissions  
  • Continuous authentication  
  • Detailed access logging  

Organizations maintain tighter control over sensitive resources. 

9. Lack of Visibility 

Many organizations simply don't know: 

  • Which APIs exist  
  • Which applications are exposed  
  • Who has access  
  • Where sensitive data resides  

Limited visibility delays incident detection and increases breach impact. 

How Akamai Helps 

Akamai provides centralized visibility across: 

  • Applications  
  • APIs  
  • Users  
  • Devices  
  • Network traffic  

Security teams gain actionable insights for faster response and stronger governance. 

Why Zero Trust Matters 

  • Traditional security assumes users inside the network can be trusted. 
  • Zero Trust follows a different principle: 
  • Never trust. Always verify.
