McKinsey Consultant Turned Into Cyber Security Keynote Speaker Training Top UK CEOs on Cybersecurity

Edgar Perez, author of The Speed Traders and Knightmare on Wall Street, partnering with Terrapinn Training in 3-Day Masterclass Cybersecurity to bring key insights for CEOs and board members on cyber security.

London, UK — Mr. Edgar Perez, author of The Speed Traders and Knightmare on Wall Street, is addressing senior executives from the United Kingdom and Europe at 3-Day Masterclass Cybersecurity organized by Terrapinn Training. Perez is a well-known international futurist and keynote speaker who currently offers Cybersecurity Due Diligence and Awareness Training services for Fortune 500 firms and private equity groups.

As information technology becomes ever more complex and Internet usage increasingly widespread, cybersecurity is becoming an increasingly important and business-critical field. Unfortunately, most organizations are not prepared to handle cybersecurity threats. In fact, 66% of IT and security professionals say that their firms are unprepared to recover from a cyberattack. A key example of this unpreparedness is the fact that many of the companies impacted by the recent WannaCry attack didn’t install critical updates into their Windows infrastructure that had been released by Microsoft back in March.

Perez’s workshops bring CEOs, board members and top executives up to speed on the most recent and battle-tested approaches to protect their companies’ valuable information and intellectual property from prying eyes of hackers and competitors, and leverage their cyber success in both cultivating stronger relationships with current and new clients and safeguarding the interests of all stakeholders, partners and employees.

Perez, author of Knightmare on Wall Street and The Speed Traders, is a recognized futurist, keynote speaker and director of programs targeted at board members, chief executive officers and senior executives looking for new ways to gain and maintain a competitive business advantage.

RECENT TESTIMONIALS
• “The team that Edgar has assembled is top-notch. There are no words to express our satisfaction with your high-quality delivery.” Member of the Board of Directors
• “After working with a number of vendors, we found your team to be in a qualitatively different level. By that I speak to your deep expertise and exemplary professionalism.” Divisional Chief Information Officer
• “Thanks for the great work training our employees. You really made a difference!” Global Chief Information Security Officer
• “The program provides a comprehensive approach for any organization to lead in cybersecurity readiness.” IT Security Coordinator

SPEAKER’S KEYNOTE TOPICS
• The Importance of the Cybersecurity Framework for Directors and CEOs
An email embedded with malware. Security systems hacked by thieves. Credit card numbers stolen from store purchases. There’s certainly no shortage of examples when it comes to data security breaches and the havoc they wreak on business. No wonder then that nearly a third of CEOs in KPMG’s latest global survey identified cyber security as the issue having the biggest impact on their companies today. Every organization should apply a Cybersecurity Framework for analyzing cyber security, and ideally it should be integrated into an organization’s existing enterprise risk framework. The key is making it part of the mainstream of risk management within an organization. The most innovative companies today have recognized that cyber security is a customer experience and revenue opportunity, not just a risk that needs to be managed. Mr. Perez will explain why this must done across the entire organization and why the CEO and Board of Directors have the most important role to play.

• Finance in the New Global Economy
Until quite recently, globalization was seen as a one-way street. Multinationals, which led the charge four decades or so ago into growing global markets, were its ambassadors, and American and European workers, whose wages and upward mobility were flattened, were feeling left out. The core idea was that globalization, technological innovation and unfettered free trade would erase historical and geographic boundaries, making the world ever more economically interconnected and alike. Developed economies would come under more and more competitive pressure from eager upstart nations. Now we are entering a new age of volatility. Financiers will become less important, manufacturers more so. Blue collar jobs will go high tech. Robots will replace Chinese workers. Mr. Perez will discuss why finance stands now in front of its biggest transformation triggered not by any of the financial conglomerates that dominate the world today but by obscure startups that could be working already in garages in Silicon Valley, Shanghai, Kiev or Delhi.

• The Biggest Risks for Financial Markets
Constant regulatory changes and technological evolution have transformed the financial landscape so profoundly since the advent of the first electronic networks in the early 1970s. Regulators around the world are now in a race to respond to the evolution of technology in financial markets and prevent its operational challenges from becoming the biggest risk for financial markets. However, when considering technology and the cyber landscape, errors are bound to happen. Financial services firms are expected to have deployed the most sophisticated defense systems against cyberattacks. Trading firms are expected to have controls in place and invest in the technology to keep up to date. Most companies would realize the need of these investments and honestly attempt to implement them, but their IT departments would soon hit a wall, because of direct involvement from senior management and boards of directors. Compliance actions against those who missed their importance will go a long way toward restoring investor confidence and limiting the impact of the biggest risk for financial markets.

• Social Engineering: The “Weakest Human Link” in Cybersecurity
Social engineering involves tricking your employees into breaching security protocols or giving away information, most often over the telephone or via email. Social engineering exploits human weaknesses rather than technology, preying upon people’s propensity towards trust in particular. Often, these exploits are used to gather information to support a more targeted cyberattack, with the initial forays based on the premise of ‘little and often’ so as not to cause concern. Employees at all levels, including senior executives, are vulnerable. Mr. Perez will explain why by improving employee awareness and introducing simple technical measures, organizations can protect themselves against social engineering techniques and the risk of a cyberattack and its potential impact on business, customers and data.

• Establishing or Improving a Cybersecurity Program
The NIST Cybersecurity Framework, which was drafted by the Commerce Department’s National Institute of Standards and Technology (NIST), comprises leading practices from various standards bodies that have proved to be successful when implemented, and it also may deliver regulatory and legal advantages that extend well beyond improved cybersecurity for organizations that adopt it early. Its adoption may prove advantageous for businesses across virtually all industries. Mr. Perez will explain why a proper Cybersecurity Program will build on the analysis of the possible areas of concern, an understanding of the company’s most critical assets, and a thorough review of Information Technology’s policies and procedures when faced with cybercrime.

Despite WannaCry Attack, Companies Still Neglecting Cybersecurity, Says Keynote Speaker in Bloomberg

Edgar Perez, author of Knightmare on Wall Street and The Speed Traders and well-recognized keynote speaker, partnering with Terrapinn Training for 3-Day Masterclass Cybersecurity to bring key insights for CEOs and board members on cyber security.

New York City, NY, USA — Despite the ongoing cyber threat, firms are still neglecting cybersecurity, said Mr. Edgar Perez, author of The Speed Traders and Knightmare on Wall Street, in a recent interview with Bloomberg Daybreak hosted by Bryan Curtis and Doug Krizner.

As information technology becomes ever more complex and Internet usage increasingly widespread, cybersecurity is becoming an increasingly important and business-critical field. Unfortunately, a recent study from security solutions provider Resilient Systems and market research firm Ponemon broke down key areas of continued failure for businesses.

The study found that 66% of IT and security professionals surveyed said their firms are unprepared to recover from a cyber attack, and 75% lack a formal incident response plan. A key example of this unpreparedness is that fact that many of the companies impact by the recent ransomware attack leveraging cryptoworm WannaCry had not installed patches in their Windows infrastructure that were released by Microsoft back in March. Vulnerabilities in commercial software are common; the only solution is to stay abreast of manufacturer’s releases, concluded Perez.

Well-known keynote speaker Edgar Perez has assembled a team of cyber experts that provides essential cybersecurity awareness training to reduce the risk that employees and partners can fall victim to sophisticated phishing or social engineering methods and unknowingly serve as entry points into the firm’s information and data systems.

New York City, NY, USA — Renown cybersecurity speaker Edgar Perez is offering 360° Cybersecurity Awareness Training services for Forbes Global 2000 companies, in the wake of the large-scale WannaCry ransomware attack that leveraged malicious software stolen from the National Security Agency and exposed vulnerabilities in Microsoft Windows computer systems in almost 150 countries.

• “Your presentation was the real highlight of the Emerging Markets Investments Summit. You clearly have the connections in the industry and are very well connected.” Alex Ritson, BBC News Presenter at The Newsroom, World Business Report and Business Matters (United Kingdom)

• “I would like to show my appreciation on your willingness to share your insights about cybersecurity. We would certainly have you in mind as we move forward to deal with this very important issue.” Nik Hasyudeen, former President of the Malaysian Institute of Accountants (Malaysia)

THE LARGEST RANSOMWARE CYBER ATTACK EVER

According to The New York Times, malicious software, transmitted via email and stolen from the National Security Agency, exposed vulnerabilities in computer systems in almost 150 countries in one of the largest “ransomware” attacks on record.

Cyberattackers took over the computers, encrypted the information on them and then demanded payment of $300 or more from users to unlock the devices. Some of the world’s largest institutions and government agencies have been affected, including the Russian Interior Ministry, FedEx in the United States and Britain’s National Health Service.

As people were fretting over whether to pay the digital ransom or lose data, attackers might be pocketing more than $1 billion worldwide before the deadline runs out to unlock the computers.

While most cyberattacks are inherently global, this one seems more virulent than most. It had spread to all corners of the globe, with Russia hit the worst, followed by Ukraine, India and Taiwan, said Kaspersky Lab, a Russian cybersecurity firm.
