Comunicações unificadas

Whether it’s a quick message to a colleague, a video call with a remote team, or a conference with clients, staying connected keeps everything moving. But when messages, calls, and meetings happen across different platforms, things get messy — missed updates, delayed responses, and scattered workflows.

Unified Communication (UC) brings everything together — messaging, calls, video meetings, and collaboration tools — all in one system. For businesses, this means faster decisions, better teamwork, and fewer communication breakdowns. When everything is in sync, projects move forward smoothly, and employees stay connected — no matter where they are.

On-Premises UC: More Control, Bigger Investment

On‑premises UC runs entirely on servers owned and managed by the company, giving businesses full control over security, data, and system updates. The in‑house IT team handles all maintenance to ensure smooth and reliable operation.

Cloud-Based UC: Flexible and Cost-Effective

Cloud-based UC is hosted by an external provider, eliminating the need for businesses to manage their own servers. It’s a cost-effective solution that scales easily as the company grows and enables employees to connect from anywhere.

Hybrid UC: The Best of Both Worlds

A hybrid setup combines on‑premises infrastructure with cloud‑based services, delivering a balance of security, flexibility, and scalability. Businesses can store sensitive data on their own servers while leveraging cloud tools for remote work and team collaboration.

On‑premises unified communications (UC) keeps everything within the company’s own infrastructure, ensuring privacy, security, and uninterrupted service.
Why Businesses Choose On‑Premises UC?
Strong Security and Compliance

When communication data is stored on-site, businesses can establish their own security policies, manage access, and implement encryption without relying on third-party providers. This decreases cybersecurity risks and helps industries such as finance, healthcare, and government comply with rigorous regulatory standards.

Reliable Communication: No Internet Required

Since on‑premises UC operates within a company’s internal network, calls, video conferences, and messaging continue functioning even if the internet connection fails. For businesses that depend on uninterrupted, high-quality communication, this reliability is a critical advantage.

Adaptable to Business Needs

Unlike cloud-based systems with fixed functionalities, on-premises UC allows businesses to tailor their setup to specific requirements. They can integrate UC with existing software, support systems, and industry-specific applications to optimize workflow efficiency.

Long-Term Cost Efficiency

Although initial implementation of on-premises UC incurs higher costs, eliminating recurring cloud subscription fees leads to savings over time. Businesses with established IT infrastructure benefit from reduced operating expenses while retaining full control over their communication ecosystem.

Maintenance and Updates on Your Terms

Cloud-based platforms update according to the provider’s schedule, which may occasionally disrupt operations. With on-premises UC, organizations decide when to deploy updates, ensuring seamless transitions and compatibility with internal systems.

AI Assistance

Artificial intelligence now assists businesses by drafting emails, summarizing meetings, and automating routine tasks — saving time and boosting productivity.

Hybrid Work Support

Employees can work seamlessly from home, the office, or on the go, using tools designed to support flexibility and collaboration from anywhere.

Better Integrations

Open APIs allow meeting solutions to connect with calendars, CRM systems, and productivity apps, streamlining workflows.

Smarter Meeting Spaces

AI-powered cameras, spatial audio, and digital whiteboards make meetings more engaging. These features ensure all participants — whether in the office or remote — stay involved.

Stronger Security

As data privacy regulations tighten, meeting platforms are doubling down on security. Features such as configurable data retention policies, audit trails, and enhanced access controls help businesses protect sensitive information.

Immersive Collaboration

Extended Reality (XR) is transforming virtual meetings. Through spatial computing and 3D environments, teams can collaborate in a way that feels more natural and immersive — bringing virtual interactions closer to real-life experiences.

When choosing a unified communications solution, businesses must decide between cloud UC and on‑premises UC. Both deliver powerful communication capabilities, yet differ notably in deployment, management, cost, and flexibility. Below is a detailed comparison to guide your decision:

Businesses and organizations rely on seamless communication to stay competitive, deliver superior services, and maintain smooth operations.

Setor Corporativo: Trabalho em Equipe Mais Suave, Decisões Mais Rápidas

In today’s fast‑paced business environment, teams must communicate clearly and act swiftly. UC tools consolidate messaging, video conferencing, and project collaboration into a single platform, ensuring employees can connect effortlessly — whether they’re in the office or working remotely.

Assistência Médica: Conectando Profissionais Médicos e Pacientes

Whether it’s a doctor consulting with a distant specialist, a nurse updating patient records, or a virtual physician‑patient appointment — UC ensures these interactions happen seamlessly. Telemedicine thrives on real‑time video and secure messaging, facilitating the safe and efficient sharing of critical healthcare information.

Educação: Superando as Lacunas na Aprendizagem

UC extends the classroom beyond its physical boundaries. Teachers deliver lessons through virtual classrooms, students collaborate in groups, and universities host webinars reaching learners globally. Whether in person or remotely, education remains uninterrupted and interactive.

Finanças: Comunicação Segura e Instantânea

Speed and security are paramount in the financial sector. UC allows advisors, analysts, and clients to communicate instantly while adhering to stringent compliance standards. Secure video meetings, encrypted messaging, and document-sharing tools help keep sensitive financial data protected.

Manufatura e Logística: Racionalização das Operações

Coordinating production lines, tracking shipments, and managing the supply chain require real-time communication. UC helps factories and warehouses remain synchronized by enabling instant updates, reducing downtime, and ensuring efficient operations.

Governo e Setor Público: Fortalecimento dos Serviços Públicos

As businesses adopt unified communications (UC), they face increasing security risks. Cybercriminals target these systems to steal data, gain unauthorized access, or disrupt operations. Protecting UC platforms is essential for securing business communication.

Increased Risks with UCaaS & BYOD

Many organizations now use UCaaS and allow employees to work from personal devices (BYOD). While this facilitates collaboration, it also amplifies security risks. With UCaaS, organizations depend in part on third-party providers’ security measures. BYOD introduces sensitive corporate data across multiple personal devices, complicating access control and threat prevention (such as malware, phishing, and unauthorized access).

API Vulnerabilities & Credential Theft

Open APIs are widely used to integrate UC tools and streamline workflows. However, poorly secured APIs can become attack vectors. Cybercriminals may exploit weak authentication, stolen credentials, or unpatched APIs to penetrate systems, manipulate data, or disrupt communications.
