SquareX secures US$20 million to transform browser security

Business Mayor27-04-2025

SquareX has announced the close of its Series A funding round, raising US$20 million. The investment was led by SYN Ventures, a venture capital firm specialising in cybersecurity, with continued support from Peak XV Partners, formerly known as Sequoia Capital SEA.
The Singapore-based company has pioneered Browser Detection and Response (BDR), a solution that strengthens security directly within the browser. Its approach eliminates the need for businesses to adopt entirely new enterprise browsers, which can often disrupt user experience and productivity. Instead, SquareX offers a simple extension that turns any browser into a secure, enterprise-grade tool.
Vivek Ramachandran, CEO of SquareX, said, 'The browser is the new endpoint, yet it remains a major blind spot for most organisations. Existing solutions often force a trade-off between security and usability. We built SquareX to eliminate this compromise in browser security, offering robust protection that works with the browsers users are already familiar with. This Series A funding, led by the team at SYN Ventures, validates our vision of everyone being able to be online without fear.'
As browsers have increasingly become primary targets for cyberattacks, the need for better security solutions has grown urgent. Traditional security tools often lack the ability to monitor threats at the browser level, and adopting proprietary enterprise browsers can create friction in daily workflows.
SquareX addresses these challenges with its BDR extension. It allows enterprises to detect and manage threats such as malicious extensions, phishing attempts, data leakage through generative AI, and insider threats. By operating within the native browser environment, SquareX significantly reduces the attack surface without compromising usability or requiring complex change management.
Jay Leek, Managing Partner and Founder of SYN Ventures, commented, 'SquareX is tackling one of the most significant and underserved areas in cybersecurity today. The browser is ground zero for countless attacks, and the team at SquareX has developed an elegant and powerful solution that provides critical visibility and control where it's needed most – directly within the native browser experience.'
Peak XV Partners, which first invested during SquareX's seed stage, has expressed confidence in the company's progress and direction.
'Having partnered with SquareX since their seed stage, we've been impressed by their vision and execution in tackling browser security challenges. We are excited to partner with them again as they demonstrate strong results in delivering much-needed cybersecurity capabilities to enterprise customers,' said Shailendra Singh, Managing Director at Peak XV.
SquareX's innovative approach aims to reshape how enterprises think about browser security, offering a way to protect users without disrupting their preferred digital workflows.

Rolls-Royce to build Britain's first mini nuclear reactors

Rolls-Royce will build the country's first mini nuclear power plants as part of a multibillion-pound effort to make Britain a world leader in the technology. The Derby-based engineering giant was on Tuesday confirmed as the sole winner of a design competition, beating rivals GE-Hitachi and Holtec International following a two-year selection process. It will now work with the Government on a programme to initially build three the first small modular reactors (SMRs) by the 2030s, with £2.5bn of funding pledged through 2029 and billions more expected beyond that once construction begins. Ministers said the decision showed they were 'backing Britain', with the majority of the supply chain expected to be based domestically. As a 'preferred' bidder, Rolls will now hold talks to negotiate a final contract with the Government. A location has yet to be announced but sites including Wylfa, in Anglesey, and Oldbury-on-Severn, in Gloucestershire, are among those being considered. Ed Miliband, the Energy Secretary, said the scheme would boost energy security and create thousands of jobs, as part of a new 'golden age of nuclear' that has also seen the Government pledge £14bn of new funding to the construction of Sizewell C. Rachel Reeves, the Chancellor, added: 'The UK is back where it belongs, taking the lead in the technologies of tomorrow with Rolls-Royce SMR as the preferred partner for this journey. 'We're backing Britain with Great British Energy - Nuclear's ambition to ensure 70pc of supply chain products are British built, delivering our plan for change through more jobs and putting more money in people's pockets.' SMRs would in theory be faster to build than larger nuclear plants, such as Hinkley Point C and Sizewell C, and come with smaller price tags – although they remain unproven commercially. Tuesday's announcement also confirmed cutbacks to the SMR programme, which The Telegraph previously revealed were being considered. The Government had earlier suggested that two or as many as three SMR manufacturers would be chosen to take designs forward, with nuclear industry insiders saying this would boost competition and ensure a 'backup' was available should the main winner run into trouble. But with the Treasury under pressure to find billions of pounds for other priorities such as the NHS and police forces, the scale of the programme now appears to have been trimmed back. Ministers also confirmed that Great British Nuclear, the quango set up to manage the new mini-nuclear programme, would be absorbed into Mr Miliband's publicly owned Great British Energy. Tufan Erginbilgic, chief executive of Rolls-Royce, said: 'This is a very significant milestone for our business. 'It is a vote of confidence in our unique nuclear capabilities, which will be recognised by governments around the world.' Rolls has also been selected by the Czech government to build some of Europe's first SMRs in a joint venture with state energy firm CEZ. The decision brings to a close a process that was first promised by George Osborne, the former chancellor, in 2015 but did not begin until 2023 under the previous Conservative government. Rolls was widely viewed as the frontrunner in the process and had already been awarded £210m of taxpayer support in 2021 towards the development costs of its SMR technology. But in the past year, ministers have faced calls from Rolls boss Erginbilgic to push forward more quickly to ensure Britain retains 'first mover advantage'. The global SMR market is projected to be worth up to £500bn by 2050, according to the International Energy Agency. Rolls is vying against companies including Westinghouse and GE-Hitachi to secure customers and set up supply chains. The company has long supplied the pressurised water reactors that power Royal Navy submarines but has more recently sought to develop SMRs and even smaller 'micro reactors' for commercial use as well. Its SMRs would be constructed from 'modules' that are built in factories and then transported to sites for assembly. The idea is meant to ensure that the plants can be produced efficiently at scale and more quickly than larger nuclear projects. As part of the SMR competition, the Government asked companies to explain how they would bring down costs over time. In the longer run, it is also hoped that the smaller price tags of SMRs will ensure they are more attractive to private investors, which have long viewed bigger plants as too expensive and risky to back without government support. Major technology companies including Google, Amazon and Facebook owner Meta are investing in potential SMR technologies, amid suggestions they could eventually be used to supply power-hungry data centres needed to develop artificial intelligence.

US Telecoms Face Capex Decline Amid Economic Challenges: A Review of Key Operators Including AT&T, Verizon, Charter, Comcast, T-Mobile (DT), Lumen, Frontier, and More

The brief analyzes the US telecom capital expenditure trends, using data from key operators like AT&T and Verizon. In 2024, US telco capex was $80.5 billion, but with concerns over inflation and recession, spending is expected to decline. Telcos are leveraging AI for operational efficiency, amid economic and policy uncertainties. Dublin, June 10, 2025 (GLOBE NEWSWIRE) -- The "US Telco Capex Fading as AI Giants Take Center Stage" report has been added to offering. This brief examines the near-term outlook for telecom capital expenditures (capex) in the US, based on the 1Q25 earnings of key operators, including AT&T, Verizon, Charter, Comcast, T-Mobile (DT), Lumen, Frontier, and more. It analyzes how current spending patterns compare with previous forecasts, highlights the main forces shaping investment decisions, explores implications for vendors, and discusses trends in emerging areas such as AI, large language models (LLMs), and data centers. The US market closed 2024 with $80.5 billion in telco capex and $505.2 billion in revenues, representing 27% and 28% of global industry totals, respectively. The USA's capex to revenue ratio, or capital intensity, was in the 17-18% range in 2022-23. That was well above historic levels. The ratio started to moderate in 2024. For full-year 2024, capital intensity was 15.9%. Based upon 1Q25 earnings calls and other datapoints, that will fall further. US telcos are looking to monetize recent investments, and more focused on conserving capital and cutting costs. Economic and policy uncertainty continues to be high, with inflation and recession fears stemming from the presidentially contrived trade emergency. As telcos conserve capex, they must see irony in the massive investment bubble in the data center market. Telcos are struggling to attract the same investor interest. However, telcos are finding other ways to benefit from AI in the US. They aren't positioned well to ride the GenAI wave, but they are deploying AI-based technologies to deliver operational efficiency. For instance: AT&T: using AI to improve call center automation, software development, and digital acquisition. The company says that investment in automation is helping offset labor costs and drive self-service efficiency across sales and support channels. Verizon: integrating AI into customer care and network ops; use cases include predictive maintenance, customer service automation, and internal process efficiencies. Comcast: AI is deployed across billing automation, network troubleshooting, and customer service, reducing truck rolls and call center loads. Machine learning models are used to predict customer churn and drive targeted promotions. Charter: has invested in AI for years, focused on frontline efficiency and self-service; it is reducing repair calls and truck rolls. Internal tools are used to optimize operations, enhance agent support, and reduce OPEX. DT/T-Mobile: AI is integral to DT's digital transformation, aiming at €800 million in group cost savings by 2027. AI is used to optimize fiber rollouts, automate customer service (e.g., chatbots solving 50% of issues without humans), and remotely manage 75% of routers. DT says that AI supports operations across service, coding, sales, and mobile RAN monitoring. Lumen: Lumen is positioning itself as a backbone provider for the AI economy. Lumen Digital platform uses AI for automation and real-time network control. Over the next few quarters, US telcos will remain tightly constrained on capex. Weaker economic growth will hit revenues. Rising government debt and tariffs will cause inflation to spike. Fewer international visitors to the US, less foreign investment, both lead to weaker demand. Tariffs may also cause shortages or high costs in certain component parts used in building networks. Labor costs will rise, as the surge in investment from an adjacent sector (data centers) will make it harder for telcos to keep their staff. But telcos have been wrestling with such issues for years, and they will survive this as well.
