Cloud Security Reinvented: Nexigen’s Approach to Cloud Threat Protection

Share This Story, Choose Your Platform!

Quick Summary

Cloud providers secure the infrastructure, but customers carry real responsibility for configuring, monitoring, and defending their own cloud environments. Gaps in that shared responsibility model, combined with rising account takeover and business email compromise attacks, leave many organizations exposed. Nexigen helps close those gaps through risk assessment, Cloud Security Posture Management, and Cloud Detection and Response built for SaaS and PaaS environments.

Old habits die hard, and plenty of IT veterans still assume on-premises operations offer better protection than anything the cloud can deliver. The pandemic pushed even the most skeptical teams toward remote work and cloud adaptation, whether they were ready or not.

Now that the dust has settled, cloud security has become one of the top priorities on every IT roadmap, especially since attackers have shifted their focus toward cloud environments right alongside everyone else. At Nexigen, we have watched this shift closely, and confusion around cloud security practices continues to make the situation harder than it needs to be.

Understanding Your Role in Public Cloud Security

Confusion around public cloud security often starts with a simple question. Where does the provider's responsibility end and the customer's begin?

Most cloud providers answer that question through a shared responsibility model, an approach first introduced by AWS and now standard across the industry. Looking closely at this model reveals something many organizations underestimate: customers carry a genuine share of responsibility for securing their own cloud resources.

Gartner has noted that through 2024, most enterprises will continue struggling to measure cloud security risks accurately. The struggle often starts with misunderstanding this exact division of labor.

Nexigen's managed IT services team spends a good deal of time helping clients understand where their responsibility begins.

The Obstacle Course of Public Cloud Security

Accepting responsibility for cloud security is one thing. Putting effective measures into place is another challenge entirely.

Cloud provider security settings tend to prioritize ease of use over strong protection. Convoluted interfaces and inconsistent methods for adjusting settings and policies turn a simple task into a genuine obstacle course for IT teams already stretched thin.

The security marketplace complicates things further. Most available tools focus heavily on IaaS, a well-known attack surface, while SaaS applications like Microsoft 365 and Google Workspace receive far less attention despite carrying serious risk. That gap has contributed to a sharp rise in damages from account takeover and business email compromise attacks, both of which continue climbing year over year.

Many tools on the market also simply echo data already generated by the provider itself. Relying on this kind of surface-level reporting, including native dashboards like the Microsoft Office 365 Security Center, can create a false sense of protection. Nexigen's security professionals have observed that cloud security measures across sectors are frequently deployed inadequately, leaving environments more exposed than most organizations realize.

The Nexigen Plan of Action

Strengthening a cloud environment and responding to cloud-based threats should follow the same logic applied to any enterprise technology component:

●       Assess vulnerabilities: Evaluate cloud resources against recognized standards and best practices

●       Prioritize remediation: Address risks based on their probability and potential impact

●       Monitor continuously: Build the capacity to detect and respond to threats before they escalate

Integrating cloud environments into enterprise risk management requires a level of agility that traditional IT security rarely demands. Nexigen recommends a Cloud Security Posture Management (CSPM) tool that covers public cloud IaaS and major SaaS providers together.

Feeding accurate threat data from cloud instances into a SIEM or other monitoring tool matters just as much. Organizations equipped to respond to cloud-based threats and proactively search for signs of compromise stand a far better chance of catching problems before they spread. Nexigen's cloud and SaaS security team builds these capabilities into every strategy developed for clients navigating this shift.

Cloud Detection and Response

Cloud Detection and Response has become a core managed service offered to Nexigen clients. Data continues to move to the cloud through SaaS and PaaS solutions, away from servers and endpoints on-premises. This created a genuine need for real-time systems capable of responding to attacks that never touch on-premises infrastructure at all.

Recent reports show that business email compromise incidents are hitting central identity management services at twice the previous rate, and legacy weekly IOC scans simply cannot keep pace with that speed. Nexigen upgraded to a modern toolset that monitors activity across SaaS and PaaS systems continuously.

This approach also enables automation and fast response when something goes wrong. Think of it as EDR built specifically for the cloud, watching over the systems that traditional endpoint tools were never designed to see.

Building Cloud Security That Actually Holds Up

Cloud security demands more than trusting a provider's default settings or a dashboard that only echoes data already visible elsewhere. Understanding the shared responsibility model, closing gaps in SaaS protection, and building real-time detection into cloud environments together form a security posture that can withstand modern threats.

Remote work and cloud computing aren't going anywhere, and neither are the attackers targeting them. Talk to Nexigen about building a cloud security strategy designed for the environment your business actually runs today.

FAQs

What is the shared responsibility model in cloud security?

The shared responsibility model outlines which security tasks belong to the cloud provider and which fall to the customer. Most providers secure infrastructure while customers manage configuration and data protection.

Why is SaaS security often overlooked?

Most cloud security tools focus on IaaS environments, leaving SaaS platforms like Microsoft 365 and Google Workspace with less coverage despite rising account takeover and business email compromise attacks.

What does a CSPM tool do?

A Cloud Security Posture Management tool assesses cloud configurations against recognized standards and enables near real-time detection and enforcement across IaaS and SaaS environments.

How does Cloud Detection and Response differ from traditional monitoring?

Cloud Detection and Response monitors SaaS and PaaS activity directly, catching threats that never touch on-premise servers or endpoints. It’s unlike legacy tools built around on-premise infrastructure.
