Communication is a cornerstone of business success in 2025. Not only does seamless communication enhance team productivity by as much as 25%. Friction-free communication is also fundamental for providing outstanding customer support and a great customer experience.

To take their communication to the next level, enterprises now typically leverage unified communication platforms, which are flexible and scalable and come with a wide range of additional features, high-level security, and numerous integrations.

Here are the top five enterprise-grade communication platforms that dominate the market in 2025.

Nextiva

At the top of our list is Nextiva, a market-leading provider of unified communications and customer experience solutions. Nextiva offers a comprehensive set of communication channels, including voice and video calls, live chat, messaging, file and screen sharing, SMS, and social media. Going further, users also have access to an advanced set of features to make workflows more efficient such as interactive voice response, AI-powered analytics, intelligent skills routing, and automatic call transcripts. For enterprise clients, Nextiva also offers a unified team interface and a supervisor dashboard for optimal leadership.

One of Nextiva’s stand-out features is their award-winning customer service, which is available 24/7 to help users whenever they have questions.

Nextiva also implements top-notch security protocols, including end-to-end encryption via Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP). They regularly conduct third-party audits of their systems, in collaboration with white-hat hacker communities. As for physical security, Nextiva’s data centers are audited and certified to meet ISO/IEC 27001 standards, include biometric security checkpoints, and are set up with several redundancies and uninterruptible power sources (UPS) in case of natural disasters.

Finally, Nextiva also convinces with its broad range of integrations with other enterprise-grade platforms, such as customer relationship management (CRM) solutions like Zoho, HubSpot, Salesforce, and Zendesk.

Microsoft Teams

Next up, there is Microsoft Teams, a communication solution that is less streamlined but widely used at corporate level because of its seamless integration with the Office 365 suite of tools. It’s the company’s designated Skype successor.

In terms of communication channels, Teams offers video conferencing, chat, and collaboration features that can help teams work together efficiently. However, Teams’ capacity for customer-facing communication is limited in comparison to platforms such as Nextiva.

On the upside, Microsoft Teams can boast a large range of integrations with other business platforms – over 600, in fact. This means it is likely to integrate perfectly into the IT ecosystem that enterprises already use.

Like Nextiva, Microsoft Teams also harnesses industry-standard encryption protocols to guarantee secure communications.

Cisco Webex

Another top choice among enterprise-grade communication platforms is Cisco Webex. This platform comes with voice calling and video conferencing, team chat text messaging, as well as options for holding webinars and online events

What makes Cisco Webex stand out is its focus on security and AI-based support tools. Some of its key features include an AI assistant that generates call transcripts and summaries and an admin-facing “Ask AI” assistant. For international teams and global meetings, Webex also offers real-time translation into 13 spoken and over 100 captioned languages.

As part of its video conferencing features, Cisco Webex also offers handy features like breakout rooms, polling, and whiteboards. Its team chat also makes presence monitoring, file sharing, and sending audio clips possible.

In terms of security, Cisco Webex offers end-to-end encryption on calls, as well as password-protected meetings and different data residency options. Their standards meet those set by organizations with rigorous compliance requirements, such as ISO and FedRAMP.

As for integrations, Cisco Webex connects to over 140 other business platforms.

Zoom

Among enterprise-grade communication platforms, few are better known than Zoom, which has become a staple in enterprise communications over the past few years.

Initially known for video conferencing, Zoom has since extended its range of functionalities to cater to the needs of enterprises. It now includes voice and video calls, team chat, event and webinar hosting, as well as text messaging (on certain plans).

Like Cisco Webex, Zoom also offers an AI companion that can generate transcripts and summaries of calls. Its online event features are more advanced and include individual branding as well as registration management and a larger suite of interactive features. Zoom’s team messaging capabilities include file sharing as well as a searchable history and separate channels for different projects and teams.

Like Cisco Webex, Zoom also provides security through end-to-end encryption, waiting rooms, and password protection, in compliance with both HIPAA and GDPR.

Thanks to its ubiquity, Zoom now offers over 1,000 integrations and apps in its marketplace.

8×8 X Series

Rounding out this list of the best enterprise-grade communication platforms is 8×8, which, like Nextiva, offers an extensive set of cloud-based communication options and contact center functionalities aimed to enhance customer experience.

8×8 offers voice calls, video conferencing, and messaging channels. Their X series plans include helpful features like advanced call routing, auto attendants, and automatic call transcription. Users can also leverage AI for meeting summaries, automated polls, and noise suppression among other features.

Furthermore, 8×8 offers native integrations with a wide range of other business platforms, from CRMs and conversational AI providers to workforce engagement management and employee experience providers.

Communications are fully encrypted and 8×8 is compliant with a large set of international standards, including among others HIPAA, CPNI, ISO 27001:2013, FISMA, NIST 80-53 R4, and the UK Cyber Essentials Plus accreditation.
