# Best Auditing Services Providers in Pittsburgh, PA *By [Nathan Calabrese](https://research.g2.com/insights/author/nathan-calabrese)* Auditing services help companies ensure their accounting records are an accurate representation of the transactions that they have made. Auditing services assist companies with constructing compliant financial statements and communication with banks, investors/shareholders, and other financial partners that their finances are in order. Auditing services are most commonly implemented in a company’s finance and accounting departments. Auditing services can often be supplemented by [financial consulting providers](https://www.g2.com/categories/financial-consulting), [bookkeeping services providers](https://www.g2.com/categories/bookkeeping-services), and [tax services providers](https://www.g2.com/categories/tax-services).

Founded to close the gap between the cameras organizations already run and the intelligence those cameras could provide, Lumana serves enterprise, mid-market, and SLED (state, local, and education) customers across retail, education, healthcare, government, hospitality, manufacturing, and logistics. Legacy video systems rely on manual monitoring, slow investigations, and fixed, rule-based analytics; Lumana applies adaptive, agentic AI to live and recorded camera feeds so video becomes searchable, real-time intelligence instead of footage that goes unwatched. The platform is camera-agnostic: it works with any IP camera and also offers a line of NDAA-compliant Lumana cameras. AI runs on-site on Lumana Core, which processes video locally, while a hybrid-cloud architecture unifies management across every location in a single interface, VMS+. Common use cases include real-time threat and safety monitoring, faster incident investigation, loss prevention, occupancy and operational analytics, and centralized multi-site security management. Main features and benefits: • VIA-1, a continuous-learning video intelligence model that adapts to each camera's environment over time and reduces false alerts by up to 90%, so teams spend less time clearing noise and more time on real events. • AI agents that automate the video security workflow across monitoring, investigation, insights, and response, including real-time alerts and automated actions such as notifications, audio messages, and webhook or GPIO triggers. • Natural language search that finds events across thousands of hours of footage in seconds by describing them in plain language, with no query syntax to learn. • Single-pane-of-glass management for every camera, site, alert, and investigation, available on desktop and mobile. • Enterprise-grade security and compliance, including SOC 2 Type II, NDAA, HIPAA, and GDPR, with role-based access control down to the camera level. Lumana is built on a hybrid-cloud architecture that scales from a single site to tens of thousands of cameras without replacing existing infrastructure. Because VIA-1 keeps learning from each deployment, detection accuracy improves in the customer's own environment rather than staying static over time. Organizations including Salesforce, Meta, McDonald's, and the University of Miami use Lumana to secure and gain intelligence from their physical environments.
