Hasta La Vista, Long-Lived Certs: Why 2029 Is The Year Everything Changes
With quantum computing breakthroughs from Microsoft, Amazon and Google over the past six months, it's starting to feel like 2029 is shaping up to be a real turning point. And no, not just because it's the year the Terminator came back to hunt down Sarah Connor.
In the world of digital trust, 2029 has its own kind of Judgment Day.
It's the year Gartner says organizations need to be quantum-ready. And as of April 14, 2025, it's also the year the industry is expected to shift to 47-day certificate lifespans, replacing the already-short 398-day standard. And it's the year organizations that haven't embraced crypto-agility may find themselves scrambling to catch up.
This isn't science fiction—it's the very real future of cybersecurity. And the clock is ticking.
The Quantum Arms Race Is Real
Recent advances in error correction, qubit stability and hybrid quantum models have put us on an accelerated path toward a cryptographically relevant quantum computer—one that could break widely used encryption like RSA and ECC. When that day arrives, the consequences won't be limited to headlines. It will affect everything: secure internet sessions, financial transactions, software updates and more.
And while that quantum day hasn't yet arrived, attackers aren't waiting. 'Harvest now, decrypt later' tactics are already in play. Sensitive data is being intercepted today, with the intent to break it once quantum capabilities catch up. For governments, enterprises and anyone dealing in IP or personal data, this is a now problem—not a later one.
The Good Guys Have a Plan: PQC + Automation
Enter post-quantum cryptography (PQC)—a new generation of encryption designed to withstand quantum threats. We are actively working with NIST, IETF and industry partners to bring quantum-safe and hybrid certificate solutions into the mainstream. NIST's selection of its first four PQC algorithms in 2024 was a major milestone, but transitioning global systems will take time.
And here's where it gets interesting: The same tools and strategies organizations need to become quantum-ready are the same ones they'll need to survive the move to 47-day certificates.
Let that sink in.
By modernizing your public key infrastructure (PKI), automating certificate lifecycle management and preparing for crypto-agility today, you're essentially killing two security birds with one stone:
• You're ready for quantum threats
• You're ready for short-lived certificate enforcement
Why 2029 Really Matters
NIST recommends public-sector organizations be fully transitioned to quantum-safe crypto between 2030 and 2035. Gartner, however, has drawn a sharper line for enterprises: be quantum-ready by 2029. That same year, browser vendors are expected to enforce 47-day certificate validity, requiring automated, scalable certificate management to keep up.
These timelines aren't random—they're the reality check for organizations still relying on manual certificate (cert) renewals or legacy encryption protocols. The digital trust infrastructure we rely on today won't stand up to what's coming.
What To Do Now?
Organizations that wait will be forced into reactive mode—facing operational risk, regulatory penalties and potential breaches. Those who act now can make a smooth, strategic transition. That includes:
• Taking inventory of current cryptographic assets/cryptographic bill of materials (CBOM).
• Implementing certificate automation across environments to support crypto-agility.
• Preparing internal policies and compliance plans for short-lived certificates.
Over the past couple of years, a number of enterprises have mapped out their PQC roadmap and implemented the tools to thrive in a post-quantum, automation-first future. The move to PQC isn't just a swap of algorithms—it's a fundamental shift in how organizations manage trust.
So whether you're facing quantum threats or chasing short-lived cert cycles, 2029 is your deadline. And as any sci-fi fan will tell you: The future isn't set—but it is coming.

Microsoft to slash 9,000 jobs in latest brutal cut amid AI push: report
Microsoft said Wednesday that it will lay off about 9,000 workers in the software giant's latest round of brutal cuts this year. The layoffs will impact less than 4% of Microsoft's global workforce, impacting workers across different teams with varying levels of experience, a source familiar with the matter told CNBC. Microsoft has already slashed thousands of positions this year as it focuses on cutting layers of management and shifting resources toward the artificial intelligence race. Advertisement Microsoft CEO Satya Nadella speaking at a conference in May. AFP via Getty Images Bloomberg reported last month that Microsoft was planning job cuts in its sales division. 'We continue to implement organizational changes necessary to best position the company and teams for success in a dynamic marketplace,' a Microsoft spokesperson told CNBC. Meanwhile, Microsoft reported nearly $26 billion in net income and $70 billion in revenue in the most recent quarter, far outperforming Wall Street estimates. Advertisement Microsoft did not immediately respond to The Post's request for comment. Its most recent layoff round in May slashed more than 6,000 jobs, or about 3% of its global workforce, as it eradicates middle management roles. The layoffs announced Wednesday similarly seek to reduce the layers between individual contributors and top executives, a source familiar with the matter told CNBC. Advertisement Microsoft said it will lay off about 9,000 workers. AP In January, the software giant axed less than 1% of its workforce based on performance in an attempt to keep up with cutthroat tech rivals, mimicking Elon Musk's 'hardcore' approach. As of last summer, the company employed 228,000 workers. It cut 10,000 roles throughout 2023. Microsoft has led mammoth layoff rounds in the past, axing 18,000 roles in a single sweep in 2014 after acquiring Finnish telecommunications firm Nokia. Advertisement The company is projecting strong revenue growth of 14% year-over-year as it expands its Azure cloud business and corporate software subscriptions. Shares in Microsoft have risen more than 17% so far this year. Meanwhile, the company is reportedly weighing whether to abandon its breakthrough partnership with Sam Altman's OpenAI. It has considered pausing talks with the ChatGPT maker if the two parties are not able to agree on the size of Microsoft's future stake in OpenAI, the Financial Times reported last month. The company will rely on its existing contract with OpenAI through 2030, according to the report. Several other software companies have trimmed their workforces this year, including homework helper Chegg and CrowdStrike, which suffered a massive outage last year that disrupted airlines, banks and the hospitality industry.

Stock Movers: Tesla Sales Tumble, Microsoft to Cut 9,000 Workers, Centene Plunges
On this episode of Stock Movers: Tesla Sales Tumble, Microsoft to Cut 9,000 Workers, Centene Plunges Tesla Inc.'s global sales tumbled for the second quarter in a row, leaving the carmaker in a deep hole to dig out from to avoid consecutive annual declines. The company delivered 384,122 vehicles during the last three months, down 13% from a year earlier. Tesla now has an almost 110,000-car deficit to overcome in the second half in order to return to growth this year. Sales did manage to exceed the most pessimistic analysts' estimates, with the most bearish projecting a more than 20% decline. Tesla shares rallied on the report, rising as much as 4% at the open of regular trading Wednesday. Microsoft Corp. began job cuts that will impact about 9,000 workers, a second major wave of layoffs this year as it seeks to control costs. Less than 4% of the company's total workforce will be impacted, a spokesperson said. The cuts will have an impact across teams, geographies and tenure and are made in an effort to streamline processes and reduce layers of management, the spokesperson said. Health insurer Centene Corp. shocked investors Tuesday when it withdrew its profit outlook on precipitously rising risks from Affordable Care Act plans, sending shares plummeting the most in almost two decades. The company appears to have been badly caught off guard by the impact of US government actions. It's an ominous sign for insurers, whose purpose is to price for risk but have lately been blindsided by it. Shares of Centene dropped as much as 35% in New York on Wednesday, the most since 2006.

Microsoft announces another mass layoff, thousands of workers affected
REDMOND, Wash. (AP) — Microsoft is firing thousands of workers, its second mass layoff in months. The tech giant began sending out layoff notices Wednesday. The company declined to say how many people would be laid off but said that it will comprise less than 4% of the workforce it had a year ago. Microsoft said the cuts will affect multiple teams around the world, including its sales division and its Xbox video game business. 'We continue to implement organizational changes necessary to best position the company and teams for success in a dynamic marketplace,' it said in a statement. Microsoft employed 228,000 full-time workers as of last June, the last time it reported its annual headcount. The company said Wednesday that its latest layoffs would cut close to 4% of that workforce, which would be about 9,000 people. But it has already had at least three layoffs this year. Until now, at least, the biggest was in May, when Microsoft began laying off about 6,000 workers, nearly 3% of its global workforce and its largest job cuts in more than two years as the company spent heavily on artificial intelligence. Microsoft also cut another 300 workers based out of its Redmond, Washington headquarters in June, on top of nearly 2,000 who lost their jobs in the Puget Sound region in May, according to notices it sent to Washington state employment officials.
