What is Secure Web Gateway
Over half of web traffic is cloud-related, and that means that cloud-based threats are more common than ever. As such, it's vital for businesses to understand data movement between company and personal devices, apps, and services. A Secure Web Gateway (SWG) is vital for providing secure internet access and application usage to businesses in an ever-evolving threat landscape.
What is a Secure Web Gateway (SWG)?
An SWG is a mechanism for protecting users from web-based threats, enforcing company policy and filtering internet-bound traffic. An SWG can be on-premises or cloud-delivered, but either way, it sits between users and the internet to provide advanced network protection. An SWG inspects web requests and compares them against company policy to ensure access is blocked when required. With an SWG, companies can enforce their security policies, make internet access safer and protect against the unauthorised transfer of company data.
How Does an SWG work?
As we’ve touched on, instead of connecting directly to a website, users access the SWG instead, which is responsible for making the connection. However, at the same time as making the connection, the SWG performs several important functions:
- URL filtering - access to websites is controlled based on the URL categories, users, groups, or machines.
- Web visibility - not only is access controlled, but administrators can also see which websites employees access and when.
- Application control - administrators can create granular policies based on user identity and ensure that data remains private and secure.
- Data loss prevention (DLP) - data movement is monitored, and critical and sensitive information is kept within the organisation in accordance with compliance regulations.
- Advanced Threat Protection - includes anti-malware, threat intel feeds, web IPS, pre-execution analysis, cloud sandboxing, UEBA and security stack integrations with endpoints, SIEMs, SOAR, and 3rd party security solutions.
Why Does Your Business Need an SWG?
As businesses grow and become increasingly mobile, it can become extremely challenging to protect remote workers from threats. Some applications will be located on-premises, whereas others will be in the cloud. While on-premises applications will be accessed securely through a remote access VPN and data encryption, cloud applications have no such security and create significant business risk. SWGs provide secure internet access when users are disconnected from the VPN and enable organisations to gain visibility of thousands of managed and unmanaged apps and cloud services, plus web traffic.
What are the Benefits of an SWG?
An SWG is an extremely valuable solution for protecting users from cyber threats over the internet and in the cloud. It achieves that by creating a bridge for data transfer between users and the internet in accordance with company policies. Some of the key benefits of implementing an SWG include:
- Policy enforcement - with adaptive police controls for data movement, application usage and more, organisations can gain increased control.
- Improved visibility - businesses can leverage inline visibility and control across web traffic, software as a service, cloud service providers and public-facing apps.
- Threat protection - multi-layered security architecture means that malware infections are prevented and infected devices are detected before the damage escalates.
- Advanced inspection - the HTTPS inspector intercepts all traffic, describes it, and scans it, ensuring the confidentiality and integrity of communications.
- Enhanced analytics - businesses can visualise web and cloud activity, detect user behaviours and report on precise activity detail.
Could Your Business Benefit From an SWG?
With an SWG, your business can block access to high-risk websites and applications, enforce compliance policies, prevent malware infections and, ultimately, provide greater protection for both the business and its remote workforce.

Mimecast recently released its State of Email Security Report for 2021. The fifth edition of its annual report used interviews with over twelve hundred of information technology and cybersecurity professionals across the globe to gather vital cybersecurity insights. The report offers an insight into the latest email threats along with advice on how to build cyber resilience and mitigate the risks of email-borne attacks.
Cyber attacks and data breaches have been commonplace in the news headlines for some time now. Although a warning from the media is certainly helpful, there is so much more that can be done when it comes to threat intelligence sharing. Threat intelligence sharing is an important part of the global cybersecurity community effort to tackle cybercrime and should form a part of every organisation’s cybersecurity strategy. Sharing cyber threat intelligence enables organisations to make informed decisions about their cybersecurity, building more effective and robust cyber defences.
One of my favourite annual reports to read is the Verizon Data Breach Investigations Report. It’s packed full of insights about the threat landscape and security leaders, in my opinion, should read this report to get a pulse on what’s happening in cyber-scape.
After all, as cyber leaders, we are here to stop breaches – so the insights gained from real cyber incidents and breaches is gold in learning how to tighten up our defences.
All businesses, large and small, are under increasing pressure to demonstrate that they are managing the risk of cyberattacks. This means having the right processes and controls in place to identify risks and vulnerabilities, protect information, as well as detect, respond, and recover in the event of cybersecurity incidents. As such, many businesses are turning to certification authorities and security frameworks to demonstrate privacy and security best practice and achieve compliance with regulatory bodies. System and Organisation Controls (SOC 2) is one such compliance framework that can help organisations to create a structured approach to cybersecurity.
Frost & Sullivan has recently released its 2021 Frost Radar: Email Security report, where its findings provide a benchmarking framework to help businesses protect their email from cyber threats.
As we operate in an increasingly digital world, every business collect, store, and share more and more data. And, amongst that data is personal information. With the OAIC marking this year’s Privacy Awareness Week (PAW) from Monday 3 May to Sunday 9 May 2021, it’s time for us all to review how we protect our customers’ personal information.
