Zubayaa Public Key Infrastructure (PKI) Secure File Transfer Protocol as a Service (SFTPaaS)

Compliance-Ready Secure Data Exchange for Public and Private Sector deployments:

In an era defined by data breaches, ransomware, supply-chain risk, and increasing regulation requirements, how organizations exchange data is now a security and compliance control—not an IT convenience. Yet many organizations still rely on email attachments, ad-hoc cloud links, or unmanaged file-transfer tools to move sensitive information. That approach introduces unnecessary risk.

SFTP as a Service (SFTPaaS), delivered by Pinnacle Global and powered by the Zubayaa platform, provides a secure, governed, and auditable way to exchange data—without requiring organizations to build or manage the complexity themselves, and is fully GDPR compliant, ensuring safe and lawful data handling across all transfers.

What Is SFTPaaS?

Secure File Transfer Protocol (SFTP) is a mechanism for encrypted file exchange over SSH. Pinnacle Global’s SFTPaaS elevates this capability into a fully managed, enterprise-grade service, including:

Hardened, monitored infrastructure
Key-based authentication (public/private key pairs)
Identity and access governance
Centralized audit logging
Operational support
Compliance-aligned configuration

Clients receive all required details, including hostnames, URLs, usernames, and configuration guidance. Pinnacle Global manages the SFTP infrastructure, so clients do not need to worry about PKI, keys, or underlying technical setup.

Why Email and Ad-Hoc File Sharing Fail

Email and consumer-grade file-sharing tools are not compliant with sensitive data. Risks include:

Unencrypted attachments at rest
Permanent storage on mail servers
Inability to enforce least-privilege access
No revocation of sent files
Minimal or no audit trails
Accidental forwarding or misdelivery

Sensitive information such as PII, PHI, financial records, legal materials, or government data should never be transferred via unsecured channels.

Public Key Infrastructure (PKI) for Secure File Transfer

At the core of SFTPaaS is public key cryptography:

Private keys – securely stored by the client; never transmitted
Public keys – registered on the SFTP server; managed by Pinnacle Global

This eliminates password-based access and reduces the risk of phishing, brute-force attacks, or credential theft.

How Pinnacle Global Manages PKI

Public key management is often where SFTP implementations fail. Pinnacle Global treats PKI as a continuous governance function. Services include:

Key generation standards and naming conventions
Public key onboarding and registration for users and partners
Access scoping to specific users, directories, or systems
Key lifecycle management: rotation, expiration, revocation
Immediate removal of access when personnel or vendors change
Guidance for client private key storage and handling

Clients retain ownership of private keys, while Pinnacle Global ensures cryptographic trust, traceability, and compliance end-to-end.

Managed Client Applications

We guide clients in adopting secure, enterprise-grade SFTP clients (other recommended platforms), ensuring:

Key-based authentication and encryption
Role-based access
Audit logging
Integration with enterprise workflows

Clients focus on business operations, while Pinnacle Global provides repeatable, secure, and scalable systems for file exchange.

Secure Data Exchange Architecture

Using the Zubayaa platform, Pinnacle Global designs SFTP environments with:

Segmented directories per client, partner, or function
Automated inbound/outbound flows
Scheduled or event-driven transfers
Integration with internal systems and cloud services
Clear ownership and accountability

This makes file transfer part of the secure infrastructure, not a workaround.

Compliance Alignment

Our approach aligns with leading standards:

NIST SP 800-53 – Identification & Authentication, Access Control, Audit & Accountability
NIST SP 800-171 – Controlled transmission of Controlled Unclassified Information (CUI)
NIST Cybersecurity Framework (CSF) – Protect and Detect functions
CJIS Security Policy – Encryption and authentication for criminal justice data
HIPAA – Technical safeguards for electronic PHI
SOC 2 – Logical access controls and monitoring

Key-based SFTP satisfies critical requirements for regulated and public sector contracts.

Onboarding, Enablement, and Training

Security is effective only when properly used. Pinnacle Global provides:

Architecture and requirements assessment
Secure onboarding for internal and third-party users
Public key creation and validation
Client configuration guidance
Operational runbooks and documentation
Ongoing advisory and lifecycle management

We teach organizations how to leverage SFTPaaS securely and efficiently.

Auditability and Visibility

Every exchange is fully auditable, providing:

Detailed access logs
File transfer tracking
Timestamped records for compliance
Support for retention and review requirements

Auditors can easily verify secure data exchange.

Common Use Cases

Ideal for:

Government agencies and contractors
Healthcare providers and insurers
Financial services and accounting firms
Legal and compliance teams
HR and payroll data exchange
Vendor and partner file ingestion
Secure reporting and batch transfers

The Bottom Line

For organizations pursuing public sector, regulated industry, or enterprise contracts, secure file transfer is not optional—it is a baseline compliance requirement. Pinnacle Global Services, powered by Zubayaa, delivers managed, auditable, and PKI-aligned SFTPaaS, including all technical details, PKI management, and secure client guidance.

Secure the data. Govern the access. Prove compliance.
