HIGHLIGHTS

Sigma Lithium signed on July 24, 2024 a deferred US$ 22.4 million letter of credit (the “Transaction”) with Banco do Brasil. This Transaction strengthens Sigma’s commercial power, enabling it to offer 90-day “export vendor financing” to its clients at very low interest rates.The Transaction amount was calculated based on the 22,000t July 5th production and shipment at the price of 8.75% of Lithium Hydroxide quoted at LME.The Transaction represents the inaugural solution for the Company developed in tandem with Banco do Brasil to deepen Sigma Lithium’s commercial partnerships during the seasonal lithium purchase cycles.As a result of the Transaction, Sigma Lithium will gradually phase out existing trade finance lines (drawn but mostly unused in the Company’s treasury) and move from a position of receiving advance payments (at a higher cost) to providing vendor financing and widening its client base.The Transaction allows Sigma Lithium to further improve its competitive position by strengthening commercial flexibility with the goal of institutionalizing a premium for its lithium concentrate.The Company’s ability to access this category of export financing demonstrates it has achieved maturity as producer within its first year of operations.

SÃO PAULO, Brazil, July 29, 2024 /CNW/ — Sigma Lithium Corporation (“Sigma Lithium” or the “Company”) (NASDAQ: SGML, BVMF: S2GM34, TSXV: SGML), a leading global lithium producer dedicated to powering the next generation of electric vehicles with carbon neutral, socially and environmentally sustainable lithium concentrate, is pleased to announce it signed an inaugural deferred US$ 22.4 million letter of credit for export financing with Banco do Brasil at very low interest rates.

As Sigma matures as an industrial producer and demonstrates its ability to consistently deliver its Quintuple Zero Green Lithium, it gained access to access low-cost trade finance mechanisms through Banco do Brasil, available to the country’s largest industrial exporters. These agreements enhance Sigma Lithium’s commercial flexibility and market access.

As a result of the lower interest export credit lines, the Company will phase out the existing trade lines in its treasury, thus decreasing the Company’s recurring interest expenses and further improving its competitiveness.  

Ana Cabral, Co-Chair and CEO of Sigma Lithium notes, “We have reached a significant milestone in our journey as a producer, achieving the maturity to access trade financing instruments available to Brazil’s largest exporters. We are honored to be working with Banco do Brasil, the country’s largest bank, which has extended through its balance sheet in Asia highly competitive interest rates to Sigma Lithium. Banco do Brasil has a history of more than a century in fostering the development of industrial exporters in the country. With this inaugural Transaction with Sigma Lithium, one of the world’s largest producers of industrial lithium materials, Banco do Brasil strengthens its leading position in developing the Brazilian green industrialization of future facing battery materials.”

“Maintaining a consistent shipping schedule, demonstrating our product quality and low costs, as well as our ability to market to downstream battery and auto makers, has opened these additional credit opportunities for Sigma. The Transaction enhances the Company’s flexibility in how it markets its Quintuple Zero Green Lithium, ultimately helping to institutionalize a price premium that reflects its superior chemical qualities.”

DeepKeep Demonstrates Superior Multilingual AI Security Performance in New Benchmark Study

Published

on

By

As the gap in the multilingual security of AI guardrails grows, new benchmark research reveals that DeepKeep’s ability to detect prompt injection and PII across languages outperforms others, including Meta and Nvidia

TEL AVIV, Israel, July 22, 2026 /PRNewswire/ — DeepKeep, the end-to-end AI security platform, today unveiled the results of a new benchmark study showcasing significant improvements in the performance and efficiency of its multilingual AI security solution. The research study compared DeepKeep’s approach to other guardrails and LLM-as-a-Judge methods and demonstrated that DeepKeep’s multilingual capability provides superior accuracy and consistency.

As organizations deploy AI tools across global teams, the prompts and interactions these systems process increasingly span multiple languages. However, many AI security systems today are designed primarily for English-language prompts, and the consequences are measurable. A Brown University study found that translating unsafe inputs into low-resource languages got GPT-4 to engage with harmful requests 79% of the time, versus under 1% in English. As enterprises deploy AI globally, attackers can exploit this gap by issuing malicious prompts in other languages to bypass guardrails. While translation-based security solutions exist, these often introduce latency, lose context, or produce inconsistent results across languages, creating a growing security blind spot for multinational enterprises.

DeepKeep directly analyzes the semantic meaning of prompts and responses across languages using a cognition-based analysis, allowing the system to classify data without translating it into English first. The cognition-based solution can deliver an interpretable response, allowing the system to learn and improve in time. Due to their design, DeepKeep’s guardrails can efficiently handle zero-day attacks. The guardrails are also designed to handle mixed-language prompts seamlessly – a scenario increasingly common in enterprise environments where users combine multiple languages within a single AI query.

In benchmark testing against widely used open source models, including Meta’s LLaMa Prompt Guard and Nvidia’s NeMo, DeepKeep significantly outperformed in detecting prompt injection attempts and Personal Identifiable Information (PII).

The evaluation used several widely recognized prompt injection datasets, including SafeGuard, Wild Jailbreak, and Alpaca, with test sets translated into 12 additional languages including Japanese, German, Spanish, French, Italian, Korean, Dutch, and Portuguese. Across these benchmarks, DeepKeep achieved F1 scores approaching 0.98 in prompt injection detection while significantly reducing false negatives compared to translation-based guardrail models.

The platform maintains consistent security decisions across languages while operating with smaller, more efficient model architecture. DeepKeep’s multilingual classifier operates with a model of roughly 400 million parameters, which is significantly smaller than many guardrail models that rely on multi-billion-parameter architectures, enabling faster inference and lower latency in enterprise deployments.

“AI security has largely been built around the assumption that prompts are written in English or that translation is sufficient. That assumption no longer reflects how enterprises actually use AI,” said Yossi Altevet, CTO and Co-Founder at DeepKeep. “As AI systems are deployed across global teams and markets, security models must understand intent across languages, not just words. That shift requires a fundamentally different approach to how AI interactions are analyzed and protected, and we’re proud to have created a solution that meets this challenge with flying colors.”

DeepKeep’s multilingual security solution is part of the company’s established suite of enterprise AI security solutions that give businesses the confidence to leverage AI without sacrificing safety, control, or trust.

BOXX Insurance Futureproofs AI Coverage Ensuring Protection Against Deepfakes & Social Engineering

Published

on

By

TORONTO, July 22, 2026 /CNW/ — BOXX Insurance, a global cyber insurtech part of Zurich Insurance Group, today announced affirmative coverage for AI and deepfake related events for social engineering and security failures within their commercial policy offering, Cyberboxx® Business. 

New AI Endorsement Eliminates AI Coverage Grey Zone

This announcement eliminates ambiguity and cements BOXX’s commitment to providing clear cover for AI-driven incidents for their customers and their broker partners.

AI is creating new cyber and digital threats for small businesses with 86% of US business leaders with cybersecurity responsibilities reporting at least one AI-related incident in the past 12 months. In Canada, the trends follow similar patterns as 81% of Canadian businesses that experienced fraud in the past year also faced an AI-enabled attack. The sophistication of AI and deepfakes is also changing how attacks are carried out, with threat actors leveraging these tools to target and trick employees at scale via enhanced social engineering attacks.

“Threat actors are exploiting trusted relationships amongst employee and executive networks which can result in handing over credentials or misdirecting payments without an actual breach,” said Erik Tifft, Global Head of Underwriting at BOXX Insurance. “That’s why we’ve updated our policy language to address the real risks that businesses, executives and their employees face in the age of AI.”

Pairing AI & Deepfake Coverage with Each and Every Loss Reinstatements for Full Policy Term Protection

This endorsement, coupled with BOXX’s First Party Each and Every Loss, keeps coverage available throughout the policy period by reinstating the policy Aggregate Limit of Liability after each cyber incident. As AI-driven social engineering and deep fake losses ramp up, the risk of having multiple claims over a policy period increases.

“Our underwriting is keeping up with the higher frequency and the changing nature of emerging cyber and AI-driven threats,” continued Tifft, “As a result, we’re continuously enhancing our cyber insurance products with broadened, affirmative coverages to capture emerging cyber threats and new forms of cybercrime, whether they occur via systems breaches or through advanced social engineering.”

About BOXX Insurance

BOXX Insurance helps businesses and individuals insure and defend against cyber and technology risks, harnessing the power of ALL IN ONE Cyber and Technology Insurance and Protection. Headquartered in Toronto, Canada, with offices worldwide, BOXX is a global, award-winning provider of cyber protection services and technology insurance coverage.
