Alcazar Security is a crypto security firm focused on preventing losses caused by compromised keys, unsafe signing practices, and overlooked operational risks. Its team brings more than 10 years of experience in operational security and DeFi governance, including firsthand experience being targeted. Alcazar works with solo crypto holders, funds, and protocol teams to identify how digital assets could be moved or stolen.

The company offers security reviews that map signer relationships, administrative keys, upgrade paths, and the people and devices involved. Reviews prioritize potential attack paths by practical risk and provide recommendations for reducing exposure. Alcazar also helps connect ongoing monitoring to risks that cannot be fully designed away.

Its Flare service monitors wallets, multisignature Safe proposals and executions, and signer devices. Customers can route wallet activity through an endpoint to detect unexpected transactions, while alerts provide details about what moved and where, helping teams respond quickly. Alcazar combines consulting with monitoring to help clients understand their security weaknesses and act when signing activity deviates from expectations.
