Industries
While cybersecurity is a priority for enterprises worldwide, requirements differ greatly from one industry to the next. Coalfire understands industry nuances; we work with leading organizations in the cloud and technology, financial services, government, healthcare, and retail markets.

Coalfire can help cloud service providers prioritize the cyber risks to the company, and find the right cyber risk management and compliance efforts that keeps customer data secure, and helps differentiate products.

"Success" at a government entity looks different at a commercial organization. Create cybersecurity solutions to support your mission goals with a team that understands your unique requirements.

The financial services industry was built upon security and privacy. As cyber-attacks become more sophisticated, a strong vault and a guard at the door won’t offer any protection against phishing, DDoS attacks and IT infrastructure breaches.

The continuum of care is a concept involving an integrated system of care that guides and tracks patients over time through a comprehensive array of health services spanning all levels of care. Interoperability is the central idea to this care continuum making it possible to have the right information at the right time for the right people to make the right decisions.

Maintaining network and data security in any large organization is a major challenge for information systems departments. However, in the higher education environment, the protection of IT assets and sensitive information must be balanced with the need for ‘openness’ and academic freedom; making this a more difficult and complex task.

When it comes to cyber threats, the hospitality industry is not a friendly place. Hotels and resorts have proven to be a favorite target for cyber criminals who are looking for high transaction volume, large databases and low barriers to entry.

The global retail industry has become the top target for cyber terrorists, and the impact of this onslaught has been staggering to merchants. To secure the complex IT infrastructure of a retail environment, merchants must embrace enterprise-wide cyber risk management practices that reduces risk, minimizes costs and provides security to their customers and their bottom line.

Private enterprises serving government and state agencies need to be upheld to the same information management practices and standards as the organizations they serve. Coalfire has over 16 years of experience helping companies navigate increasing complex governance and risk standards for public institutions and their IT vendors.

Technology innovations are enabling new methods for corporations and governments to operate and driving changes in consumer behavior. The companies delivering these technology products are facilitating business transformation that provides new operating models, increased efficiency and engagement with consumers as businesses seek a competitive advantage.

Cybersecurity has entered the list of the top five concerns for U.S. electric utilities, and with good reason. According to the Department of Homeland Security, attacks on the utilities industry are rising "at an alarming rate".
