VPNs for Business- How do we secure our businesses in the Digital Age through Cyber Security systems?

The world today resembles a literal ‘web’; completely interconnected with networks within networks across the globe. There’s so much information that is shared out there, that data security and privacy have become paramount concerns for businesses, especially in dynamic cities like London, Tokyo, New York, etc. In such technically advanced storylines, Virtual Private Network (VPN) technology has emerged as a robust solution that people hope would protect sensitive information, maintain privacy, and enhance online security.

In this blog, we will explore VPN in detail, its benefits, uses, and how London-based companies can leverage it to strengthen their over-all digital infrastructure. Additionally, we will delve into alternative services and technologies that UK based IT companies like Portman Tech provide. This would include unified communications, IT managed services, cloud and connectivity, infrastructure solutions, and IT consultancy services, that complement and enhance the capabilities of VPN.

The history and evolution of VPNs:

The year was 1996; a certain Gurdeep Singh-Pall, along with a few of his colleagues at US Robotics, designed a technology to securely work on one’s office network from anywhere and by any type of program or computer – Point-to-Point Tunnelling Protocol (PPTP). The PC Magazine recognized it as the ‘Innovation of the Year’ – fusing the internet with the intranet with heightened security. In other words, an employee could use IP addresses to switch network packets so that he or she could privately and thus safely connect to their company’s intranet.

While Singh-Pall later went on to become the VP of Microsoft, PPTP also underwent multiple upgrades. Researchers discovered vulnerabilities in PPTP’s encryption methods and authentication mechanisms. The encryption that Singh-Pall used was found to be weak, and certain attack vectors allowed malicious actors to potentially compromise the security of the VPN connection.

These security flaws raised concerns about the overall integrity and confidentiality of data transmitted through PPTP. And this in turn led to the development of protocols like Layer 2 Tunnelling Protocol (L2TP) and Internet Protocol Security (IPsec). L2TP combined the benefits of PPTP’s ease of use with the enhanced security of IPsec, providing stronger encryption and authentication mechanisms.

IPsec (Internet Protocol Security) became one of the most widely used VPN protocols. It operated at the network layer and provided strong encryption and authentication for data transmitted between two endpoints. Another significant development was the use of SSL/TLS (Secure Sockets Layer/Transport Layer Security) for VPN connections. SSL/TLS VPNs leveraged the security mechanisms already familiar from web browsers to create secure tunnels, making them highly accessible and secure for remote access.

OpenVPN emerged as a popular open-source VPN protocol that addressed the shortcomings of earlier protocols. It combined strong security with flexibility and configurability. OpenVPN can operate over both UDP and TCP, making it adaptable to different network environments. Its open-source nature encouraged community development and security auditing, further enhancing its reliability. Today, pone can find a diverse range of VPN protocols available with IT consultants, each catering to specific use cases and security requirements. Alongside OpenVPN, protocols like WireGuard have gained attention for their simplicity and performance benefits. Additionally, advanced features like split tunnelling, multi-factor authentication, and secure access to cloud resources have been integrated in VPN services so as to further enhance the capabilities of modern VPNs.

What does VPN mean and how does VPN function?

A Virtual Private Network (VPN) is a secure and encrypted connection that enables users to access the internet or their organization’s private network while ensuring data confidentiality and anonymity. When connected to a VPN server, the user’s internet traffic is routed through an encrypted tunnel, protecting it from potential hackers and eavesdroppers.

Advantages of VPN:

  1. Heightened Cyber Security:

    VPN encrypts data, rendering it unreadable to unauthorized individuals. This is an added layer of security that is crucial when employees access sensitive company information over public Wi-Fi networks.

  2. Data Privacy:

    VPN masks the user’s IP address, thwarting websites and advertisers from tracking online activities, ensuring privacy and safeguarding against targeted marketing and data profiling.

  3. Bypassing Geo-restrictions:

    VPN allows users to access content and services that might be restricted or blocked in specific regions. This is especially beneficial for businesses that operate on a global scale or require unrestricted access to market research and competitor analysis.

  4. Facilitating Remote Work:

    With the changing work landscape, VPN enables secure remote access to company resources, promoting flexible work arrangements and increasing overall productivity.

What are the various ways in which a business in London can make use of VPN and its applications?

  1. Securing Cloud Services:

    London businesses increasingly rely on cloud-based solutions. VPN ensures secure connections between remote employees and cloud servers. This minimizes the risk of unauthorized data access and protects the business.

  2. Enhancing Remote Collaboration:

    With unified communications becoming the norm, businesses can utilize VPN to maintain encrypted and secure connections during virtual meetings, file sharing, and real-time collaboration among teams dispersed across the city or the globe.

  3. Connecting Branch Offices:

    Companies with multiple branches or locations in London can leverage VPNs to establish interconnected networks, streamlining internal communication and resource sharing.

What are the benefits of using VPN technology for your business:

  1. Safeguarding Sensitive Financial Data:

    As a financial hub, London-based companies deal with vast amounts of sensitive financial information. VPN ensures this data remains encrypted and inaccessible to unauthorized entities.

  2. Strengthening Healthcare Data Security:

    London’s healthcare industry relies heavily on digital systems to manage patient records and sensitive medical data. VPNs play a crucial role in protecting such information from potential data breaches which could jeopardize lives of millions.

  3. Ensuring Secure Legal Communication:

    Law firms in London handle confidential client information. VPN ensures that communication between lawyers, clients, and legal databases remains encrypted and confidential.

    Site-to-Site VPNs establish secure connections between multiple physical locations of a business, enabling seamless communication and data sharing. This type of VPN is particularly very advantageous for companies that have multiple offices in different geographical locations. The VPN thus installed ensures that data exchanged between company sites is encrypted, which in turn prevents unauthorized access and thus maintains the integrity of sensitive information.

  3. Intranet-based VPN:

    Intranet-based VPNs create a private network within an organization, allowing employees to communicate and share resources securely. This type of VPN is ideal for London-based IT companies seeking to facilitate seamless collaboration among team members while ensuring data privacy.

  4. Extranet VPN:

    Extranet VPNs extend the reach of a private network to trusted external entities, such as clients or partners. This fosters secure collaboration and data sharing with authorized external parties, enhancing business relationships without compromising on security.
