The cybersecurity landscape has fundamentally changed over time. There’s been a growth in ransomware attacks, cyber criminals exploit traditional security models, and as our defense mechanisms grow in sophistication, so do surrounding threats.
Perimeter-based security models, a legacy method designed for when data lived exclusively in corporate data centers, is no longer sufficient. Customers need more, and that’s where Zero Trust Architecture (ZTA) comes into play. Customer missions increasingly rely on scalable, adaptable cloud solutions, and ZTA is an essential security framework that protects every connection, endpoint, and access request.
At SAP National Security Services (SAP NS2), ZTA isn’t just a security framework. It’s a foundational element of our cloud strategy and a key competitive differentiator. Founded with the core purpose of delivering innovation to U.S. government agencies, SAP NS2 is fundamentally built on security. As a FOCI mitigated, independent, U.S. subsidiary of SAP, our teams remain dedicated to security and build on the strength of SAP’s product innovation, research and development, and legacy in the tech industry.
Understanding Zero Trust: Assume nothing, verify everything
ZTA operates on a simple but powerful principle: implicit trust isn’t granted to any user, device, or application, no matter the location or previous access history. Every transaction undergoes continuous verification to ensure identity and align with security policies. There are no shortcuts, no assumptions, and no implicit trust based on familiarity.
This security model addresses a critical vulnerability in traditional approaches, which is the domino effect of implicit trust. In perimeter-based security, applications inside the corporate network automatically trust each other. But in today’s hybrid and multi-cloud environments, one compromised application can expose multiple critical systems, placing the entire organization at risk.
Why U.S. public sector agencies need Zero Trust
As the U.S. Federal Government explores ways to accelerate, improve, and build upon the U.S. cybersecurity strategy, ZTA is a core pillar. In the recently published Cyber Strategy for America, ZTA is called out as a cybersecurity best practice. It’s a strategy that can protect National Security Systems (NSS) and mitigate malicious actors from accessing mission-critical data, and it’s important that agencies begin implementing it.
ZTA not only strengthens cybersecurity posture, but it enables agencies to operate more securely and efficiently. Organizations can better protect critical systems while supporting their modern mission needs, as ZTA provides several key operational and mission benefits:
ZERO TRUST BENEFITS FOR U.S. PUBLIC SECTOR AGENCIES
Improved mission impact
- Secure support for remote work, cross-agency collaboration, and modern digital services while maintaining strong protections for mission-critical resources
Improved operational resilience
- Reduced risk against insider threats and cyberattacks due to continuous verification, network segmentation, and least privilege access
- Continuity of operations and strengthened resilience against disruptions, even during cyber incidents
Faster ATO times
- Streamlined security reviews through standardized identity, access, and monitoring controls
- Ability to reuse controls and automate processes to achieve Authorization to Operate (ATO)
Improved time and personnel allocation
- Reduced manual security tasks through automated, centralized identity management and policy enforcement
- Newfound time for employees to focus on mission support, threat analysis, and strategic business improvements
Protected supply chain
- Secure, granular access for supply chain vendors and partners without exposing the organization’s entire network
- Identity verification and access policies to reduce the risk of third-party system access
Why Zero Trust matters for SAP NS2
SAP NS2 operates in one of the most complex and demanding security environments in the industry. We deliver secure, resilient, and compliant cloud services to industries ranging from Healthcare and Utilities to Aerospace and Defense, State and Local Governments, and Federal Agencies. These entities depend on us to protect their most sensitive data and mission-critical applications.
Supporting this diverse set of industries, where each customer may have varying accreditation needs, requires a security model that goes beyond traditional approaches. Zero Trust isn’t just a best practice for us. It’s a business imperative that enables us to:
- Deliver mission assurance across platforms, applications, and managed services
- Support both single-tenant and multi-tenant capabilities while maintaining strict isolation
- Ensure compliance with the most stringent security requirements
- Enable innovation without compromising security posture
- Strengthen our position as a trusted partner to government and enterprise customers
Implementing Zero Trust at SAP NS2
Our Zero Trust strategy aligns with Department of War (DOW) ZTA principles, while still tailoring our approach to the realities of commercial cloud operations and diverse regulatory frameworks.
We advance Zero Trust activities across all seven DOW pillars:
- User: Strong identity and access controls (ICAM) ensure every user is continuously authenticated and authorized based on risk-based policies.
- Device: Device posture validation confirms that only compliant, secure devices can access our environments.
- Network/Environment: Secure isolation of tenants and applications through micro-segmentation minimizes the blast radius of potential breaches.
- Application & Workload: Transaction-level security validates every interaction, eliminating implicit trust between applications.
- Data: Encrypted data flows across hybrid, multi-cloud, and federated networks protect information in transit and at rest.
- Visibility & Analytics: Continuous monitoring provides real-time insights into security and potential threats.
- Automation & Orchestration: Adaptive risk-based decision-making enables dynamic responses to evolving threats.
Beyond the DOW pillars, our Zero Trust implementation is built on four foundational tenets:
Transaction-level security
Layered security with micro-perimeters
Zero trust policy
Dynamic security
In support of these tenets, our customers require sophisticated isolation and security controls as they operate across varying cloud environments. We provide this through:
Tenant isolation
Accreditation alignment
Cross-domain security
Lastly, we leverage automation and integration capabilities across our security domains. This is carried out through the following strategies:
Identity & access management (IAM)
Endpoint and device security
Network segmentation & micro-perimeters
Data security tools
Analytics & CSOC integration
This integrated approach to ZTA leverages native security controls, network segmentation, and robust access management, in turn creating comprehensive protection across all of our customer environments. By integrating Zero Trust into our operations, we deliver improved efficiency, enhanced scalability, and accelerated innovation. Our secure-by-design practices make SAP NS2 a stronger partner and stakeholder when it comes to trust.
The journey, not the destination
It’s important to understand that Zero Trust has no defined end state. You never actually “arrive.” It’s an information security model that organizations must continuously refine by integrating new technologies and adapting to emerging threats.
At SAP NS2, we embrace this reality. Every new application, every system update, every change in the threat landscape requires us to reassess and refine our approach.
This continuous evolution is particularly critical for organizations like ours, operating at the intersection of commercial cloud innovation and national security requirements. Our customers can’t afford security gaps, and neither can we.
As SAP NS2 continues to advance our Zero Trust implementation, we’re not just strengthening our security posture, we’re reinforcing our commitment to our customers’ missions. Whether supporting commercial enterprises, state and local governments, or federal agencies, we ensure that security, compliance, and mission assurance are foundational to everything we deliver.
In an era where cyber threats grow more sophisticated daily and ransomware attacks threaten organizations of all sizes, ZTA isn’t optional. It’s essential. At SAP NS2, we’ve embedded it into the very fabric of our cloud strategy, ensuring that we remain a trusted partner capable of delivering secure solutions that enable innovation while meeting the most stringent security requirements.
Because in the world of national security and mission-critical operations, trust must always be earned.
