About Skyhigh Security

Skyhigh Security sells Hybrid Mesh SSE, which decouples policy management from enforcement location, so that a security policy authored once is enforced across a mesh of local gateways, virtual appliances, and global cloud points of presence. Skyhigh Security says return to office mandates, AI adoption, and cloud repatriation have changed where work happens, and that cloud-only enforcement sends local traffic on a round trip it no longer needs. Skyhigh Hybrid Mesh SSE extends Zero Trust and data protection across on-premises and cloud environments, with unified policy, local control, and up to 50% lower SSE operating costs, according to Skyhigh Security.

Skyhigh Security uses location-aware licensing to determine where inspection is done locally or in the cloud. Skyhigh Security says the cloud is used for remote users and sanctioned SaaS, and that on premises is used for campus, data center, and regulated traffic. Hybrid Mesh SSE uses Policy-as-Code to author policies once and apply them across all on-premises, remote and cloud enforcement points. Skyhigh Security says that with a single console and a single policy enforced consistently across all locations where users work, customers can reduce operation costs with fewer errors or policy drift.[6][9][11]

With the Security Service Gateway (SSG), customers can bring SSE security services such as Zero Trust access and web security closer to their users on each network. Skyhigh Security says private app access is brokered on the Secure Service Gateway, so in-network users get a local decision at LAN speed. Skyhigh Security says Secure Browser Controls enforce natively on the appliance, governing the browser session where AI work happens. Skyhigh Security says inspection and logging run on the customer's own gateway, so regulated traffic stays on the premises where it was created. Skyhigh Security says that when the cloud path is interrupted, the gateway keeps applying policy at the site.[6]

Skyhigh Cloud Access Security Broker enables organizations to embrace cloud technology while lowering their overall security risk and operating costs. Skyhigh CASB uses inline deployment modes, forward and reverse proxy, for real-time control over user access to sanctioned and unsanctioned cloud services. Skyhigh Security says Skyhigh CASB provides activity monitoring, threat detection, and data protection for company-approved cloud services such as O365, Box, ServiceNow, and Salesforce. Skyhigh Security says customers can discover sensitive data at rest within their cloud services. Skyhigh Secure Web Gateway (SWG) connects and secures a workforce directly from the cloud, without requiring backhauling traffic to the corporate network. Skyhigh Security says on-prem web policies can be migrated to the cloud with one click, without rebuilding from scratch.[9]

Skyhigh Private Access is a Zero Trust Network Access (ZTNA) solution for remote access VPN replacement. Skyhigh Security says Skyhigh Private Access provides access only to authorized apps, verifies device compliance, and delivers antimalware and DLP scanning for Private Access traffic. Skyhigh Private Access includes full protocol support for UDP traffic. Skyhigh Private Access supports any load scenario and extends cloud capacity to a global scale. Skyhigh Security describes a U.S telecommunications company that provides high-speed internet access to rural areas and replaced its traditional VPN with Skyhigh Private Access.

Skyhigh Security provides a converged DLP solution covering endpoint, web, cloud, email and private apps. Skyhigh Security describes EDM as fingerprinting of structured sensitive data stored in a file such as a spreadsheet or CSV, and IDM as fingerprinting of the content of documents such as Word, PDF, PowerPoint, or CAD documents. Skyhigh Security says Optical Character Recognition (OCR) extends DLP protection against tax paperwork, passports, credit card information or personally identifiable data that could be uploaded to the cloud or shared as images. Skyhigh DSPM continuously discovers, classifies, monitors, and remediates sensitive data at rest and inline, in real time.[11][13]

Skyhigh Security helps organizations protect their data, infrastructure, and applications from the risks associated with AI app usage. Skyhigh AI gives visibility into all AI apps in use, sanctioned, shadow and private, along with their risk attributes. Skyhigh Security says Skyhigh AI mitigates the risk of data loss, data exfiltration, unauthorized access and data breaches through AI apps. Skyhigh Security says it secures the Enterprise ChatGPT experience, enabling safe and responsible AI adoption across the organization. Legendary says Skyhigh AI lets it monitor user interactions with cloud-based AI systems and implement policies to protect creative content and regulated data.[14]

Skyhigh Security says it is purpose-built for large multinational enterprises and public-sector organizations. Skyhigh Security says it serves regulated industries including Financial Services and Insurance, Government and Defense, Healthcare and Pharma, Energy and Utilities, and Manufacturing, to secure their hybrid workforce and AI workflows while maintaining digital data sovereignty and compliance. Skyhigh Security says Skyhigh SWG holds the highest authorization of FedRAMP and continues to meet customer demand as federal and public sectors embrace cloud-delivered security solutions.[11][12][13]
