How does zero trust differ from traditional perimeter security?

Traditional perimeter security assumes that anything inside the network can be broadly trusted and focuses defenses on the boundary. Zero trust removes that assumption and requires continuous verification of users, devices and access requests, often dividing networks into smaller segments. U.S. federal guidance such as OMB memorandum M-22-09 has directed agencies toward this model, which in turn shapes what contractors are asked to build and operate.

What does it mean that SAIC is a mission integrator?

A mission integrator assembles and manages combinations of hardware, software and services to deliver an outcome for a government customer, rather than selling a single product. SAIC's stated focus covers defense, space, intelligence and civilian agencies, where programs are often large, long-running and subject to federal procurement rules. Adding specialized security expertise in-house can affect how the company positions itself as a prime contractor on those programs.

SAIC Completes Acquisition of Information Security Corporation to Expand Zero-Trust and Encryption Capabilities

Science Applications International Corp. said on October 5, 2026 that it has completed its acquisition of Information Security Corporation, a move the company links to growth in zero-trust, post-quantum cryptography and encryption work for government customers.

The Deal at a Glance

On October 5, 2026, Science Applications International Corp. announced that it had completed the acquisition of Information Security Corporation. SAIC, which trades on the Nasdaq under the ticker SAIC and is headquartered in Reston, Virginia, describes itself as a mission integrator supporting defense, space, intelligence and civilian agencies. The company said the transaction expands its capabilities in zero-trust architecture, post-quantum cryptography and encryption. The announcement was distributed through GlobeNewswire and was framed around capability areas rather than specific products or customer contracts.

Why Zero Trust Is Central to Federal Cybersecurity

Zero trust is a security model that assumes no user, device or network location is trusted by default, and instead verifies access continuously based on identity and context. U.S. federal agencies have been pushed toward this approach in recent years, notably through Office of Management and Budget memorandum M-22-09 issued in January 2022, which laid out identity, device, network and data pillars for agency implementation. That shift changes what government contractors are asked to deliver: instead of perimeter firewalls and static access rules, agencies increasingly want identity-centric controls, network segmentation and continuous monitoring. For a mission integrator, holding encryption and zero-trust expertise in-house allows it to bid on such programs with its own staff and technology rather than depending entirely on outside partners.

Post-Quantum Cryptography and the Migration Timeline

Post-quantum cryptography refers to algorithms designed to withstand attacks from future quantum computers, which could undermine widely used public-key encryption methods. The U.S. National Institute of Standards and Technology finalized its first three post-quantum standards — ML-KEM, ML-DSA and SLH-DSA — in August 2024, giving organizations concrete technical targets to migrate toward. The urgency for defense, intelligence and civilian agencies stems partly from "harvest now, decrypt later" risk, in which encrypted data captured today could be stored and later decrypted once a sufficiently capable quantum machine exists. Because many government secrets must remain confidential for decades, encryption and key-management capability represents a long-lived requirement rather than a one-time technology upgrade.

The Mission Integrator Playbook

SAIC's core business is integrating systems, software and services for government customers rather than selling standalone security products off the shelf. Federal buyers often prefer a single accountable prime contractor for complex programs, which gives integrators an incentive to own more of the security stack — encryption, key management and identity — instead of subcontracting those functions. The acquisition of Information Security Corporation fits that pattern by folding specialized cryptographic capability into a larger services organization. For agencies, the practical effect may be a shorter list of vendor relationships to coordinate on a given program; for rival contractors, it means competing against a prime that can now claim deeper in-house security credentials.

Frequently asked questions

What did SAIC announce on October 5, 2026?▾

SAIC announced that it had completed the acquisition of Information Security Corporation, according to a press release issued through GlobeNewswire. The company said the deal expands its zero-trust, post-quantum cryptography and encryption capabilities. SAIC describes itself as a mission integrator serving defense, space, intelligence and civilian agencies.

What is Information Security Corporation?▾

The announcement identified Information Security Corporation as the acquired company and tied its capabilities to encryption, zero-trust and post-quantum cryptography — the three areas SAIC said the transaction expands. The provided release focused on those capability areas rather than detailing ISC's size, product lines or customer base. Readers looking for organizational or financial specifics would need to consult SAIC's fuller disclosure documents.

Why is post-quantum cryptography a priority for government agencies?▾

Government agencies protect information that must remain confidential for years or decades, and encrypted data intercepted today could theoretically be decrypted later once quantum computing matures — a risk often described as "harvest now, decrypt later." The U.S. National Institute of Standards and Technology published its first three post-quantum standards in August 2024, giving agencies and vendors defined algorithms to migrate toward. That migration involves not just swapping algorithms but also updating key management, hardware and legacy systems across large networks.
